Well not to pimp on mine, but you need to have the shoulders flow better with the torso and neck. The wings to the extent need to have some structure to them. Anatomy is hard to find for creatures as such so try looking at a birds wing structure and see how it connects to the skeleton.
The face needs to be more developed, it seems to flow too much and as a result it seems to have a worm effect going. The spikes are over the top, the size should really decrease with the structure , so the tails' spikes need to be reduced.
Over all without knitpicking at the faults, it seems a alright mesh, if got a half decent texture, though the animation might seem buggy due to some strange poly flows.
Heres a screen dump of the wing flow and legs of my drag atm.
The poly flow isnt perfect yet, and im still finding flaws here and thier but it generally works. Since this is for an animation piece i have to make sure it will deform across the board without buggynees. Which is still does since the poor rig itself lol.
