i like it!
bit of crit: the blue eye is only noticable at x2 and the light blue pixel next to it could easily be replaced by one of your mid tone greys, and still have the same effect.
the skin seems more like skin than scales kinda like a dinasaur, texturing it might help but honestly it looks good like this, and an argument can be made that both dragon and dinosaur hide has never actually been observed.. anyways great work, ooh one last thing i noticed the front legs, the one closest to us is too short, it needs to be a pixel or two lower for sure, just look at all the feet, the front nearest us looks like its placed under the belly, physicly impossible.
A very good looking dragon :P I like the wing the best :]
awesome
