Unlike a dragon, wyverns are more bird like, most noteably so in the fact that they posses only hind legs and wings, as many dragons have front limbs and wings, or no wings at all. Both have fire or other elemental breath attacks however.

I plan on inking and coloring this soon, any comments/critiques are most appreciated.
