My overall form is pretty similar to the one of a raptor, or other bipedal dinosaur, with the addition of wings and tailwings, and a few other things. Most of my body would seem to be vaguely cylindrical, since it's almost as wide as it's high. There is no clear separation between the main part of my body and the tail. I'm built to be able to stand completely upright/vertical on my legs, and go completely horizontal for takeoff/running or carrying heavy things.

When horizontal, my hands can barely reach the ground, which make them pretty much useless as far as walking goes. My wings are made so that they can reach the ground to be used to walk on instead.

My wings are made for gliding only, and have a structure different from bat/bird-like wings. I also have a smaller pair of wings, still only for gliding, attached to my tail. They're a few feet behind my hind legs, and are the only thing that really marks the end of my real body and the beginning of the tail.

My tail is made in two section. The first, between the legs and tailwings, starts the same size as my body at the hind legs level, and slowly gets to about half that size where the tailwings attach to it. Once past the tailwings, my tail quickly gets smaller, being about an inch or two in diameter for the last few feet.

I'm somewhere between 20 and 35ft long. Don't really know the height precisely, considering i can be standing anywhere from full upright to completely horizontal. I used to say slightly over 20ft, excluding the tail, but seeing how big a 20ft+ bipedal dinosaur is, i realised that it's much smaller than what i had in mind.

If i assume that i am 20ft, my head would probably be 3.5ft long, my neck about 2.5ft, my body from the neck to the hind legs would be about 7ft, and my tail would be 4ft long for the first section, and about 3ft for the second.

(To be confirmed. I'm trying to do that mentally, and i might have that wrong.)

On the outside, i am covered by a layer of very strong, thick skin. It's rather smooth, and seems to be very strongly attached. It won't "slide", and is very hard to pinch. It's strong enough to not get shredded by sliding down along a tree trunk or on the ground.

Under this layer of skin, there are two layers of octogonal bone-like scales. These protect me from whatever might pierce the skin, help spread the pressure/force from crashlandings and other impacts, and protect me from getting crushed by locking together to form some kind of shell. The two layers are placed so that when unstretched, the second layer blocks any opening that might be left between the scales on the first layer.

My skin attaches to these scales, and can't easily slide over them. In a normal situation, the scales can't be seen unless my skin is stretched. In that situation, my skin can look a bit as if it had a bunch of flat surfaces instead of being smooth.

In addition of providing protection against physical dammage, the scales are also an important part of my immune system. Each of them contains a liquid that seals wounds and quickly creates a shell around any foreign body.

In case of serious injury or infection, my body can reject the affected scales, causing another layer of skin to form below the two layers of scales, cutting them off from the rest of my body and letting them die before replacing them.

Very dark grey, almost black, with blue stripes. The middle of my back seems almost perfectly black, and my color seems to get slightly lighter as it goes toward my underside, but stays mostly the same. The difference wouldn't be noticeable in most situations.

My stripes start in the middle of my back, and go 2/3 of the way down on each side of my body. They are in a somewhat triangular shape, getting thinner as they get closer to my underside. The space between each stripe is about twice the size of the stripe itself.

The stripes have the ability to fade to the same color as the rest of the body, or any point between. I have some control over them, to the point of being able to make them fade in and out independantly, but this requires a lot of concentration. They normally react according to emotions and health. They can go from an "pure" blue, almost glowing, to the color of the skin surrounding them. They never actually emit light, but can sometime seem to glow.

My stripes are placed in a way to never end up going over an eye, breathing opening, or limb. Only my wings arm have stripes too, looking more like bands than actual stripes. They are placed in a way so if my wings were stretched out along my back with the membrane folded, the stripes on the wings arm would match (or almost) with the ones on my back, and look as if it was the continuation of the same one.

My head is a bit wider and more massive than the regular "jurassic park-style raptor" head.

I have two different pair of eyes. The first one are where you would normally expect them to be. I think they have a blue-ish color, but i can't confirm that. I don't if they were cat-like or human like, or something else. These were used mostly to watch things at a distance, or in the dark, and had difficulty making the difference between colors.

The second pair of eyes is placed a bit lower on my snout, in front of the primary ones. These eyes are much smaller, completely black, and fit almost flat along the skin. They are made to be hard to see, allowing me to watch other creatures while my primary eyes are closed, letting them think i can't see. These are used mostly to add color information to what the primary ones see, and make depth perception more accurate. Their position and smaller size also make them harder to dammage. The image these eyes give me tend to be extremely colorfull and be sensitive to UV/IR, but has a much lower "resolution" and object too colorfull tend to look very blurry. (Colors bleeding over eachother/less colorfull things disappearing.)

Instead of having nostrils, i have 6 thin vertical opening on each side of my snout. They are placed so that air can flow into a cavity inside my snout from the 3 first, and exit by the 3 last. They seem to go almost all the way up along each side of my snout. They can close completely if needed to avoid inhaling dust or water, and can also open very wide, making my breathing much more quiet and helping pick up scents when staying still. The actual opening in my skull would be about 1in wide for each, but there's two piece of skin covering each, leaving only what's needed for breathing open, and filtering the air a bit.

On the tip of my snout, where the nostrils would be, i have two flat, slightly darker circles, which are too not very visible. I guess these are some kind of sensors, but their use is still unconfirmed. I suspect detection of electric/magnetic fields or radio frequencies of some kind, but that's really not sure. I am pretty sure that they were involved in communication between different members of our specie. ("raw data" transmission?)

My mouth is made to be used to manipulate and carry things almost more than to eat food. As a result of this, i have a high number of teeth which aren't very sharp or long. They are mostly there to make sure i have a good grip on whatever i'm holding, while avoiding causing dammage to it. I grow a new set of teeth every 10-20 years, so teeth getting broken off or dammaged are only a temporary annoyiance.

Inside my mouth, i have two acid pockets attached to my palate. They stretch from the back of my mouth to my front teeth. As long as they are empty, they stay flat against it, looking only like two bumps. They are usually empty, only filling up semi-instinctively when i'm about to eat, or when i feel threatened. The acid is strong enough to cause severe burns, but will not melt thru anything. My skin and the inside of my mouth are resistant to this acid, as it is used instead of saliva to start breaking down food when eating, or sometime to clean myself. (Or do "alien" imitations...?)

The inside of my mouth goes from the same near-black color as my skin, to a pink-red-ish flesh color near the center. Unless the acid system is being used, my mouth stays rather dry, only moist enough to prevent skin from drying too much. This allows me to use my mouth to manipulate things without having to worry about getting them all wet and slimy.

My tongue is pretty standard looking, non-forked, and can stretch out a few feet ouside of my mouth, being about twice the length as my head at most. It is prehensile and rather strong, making it almost as usefull as a hand. It has the same pink-red-ish color as the rest of his mouth, except for a somewhat wide, near black line going from the tip of my tongue to my throat along the center of it.

My ears are entirely internal, without any visible hole on the outside.

Another particularity of my head is a second bone along my upper jaw to which my lower jaw hooks up to. If needed, this bone can slide down, allowing me to open my jaws much wider than what would normally seem possible without actually unhinging.
