Leopard - flying squirrel - reptile - human splice
So I guess we can edit this, or perhaps the comments. The concept is mainly a mammal and human. The reptile-flying squirrel reference is the wings, and that's probably it. At first I was thinking scales, but then, hair/fur is predominately mammal. Elongated limbs for running, and thin arms and legs for speed. I guess, its a cheetah more than a leopard. Tail for stability. And padded palms and feet to protect against friction.
Probably hard to catch. I'm assuming, since it has wings. I wish I could take creature design, but I'll have to wait til next spring to take that class. Hm... Comments appreciated.
