Practicing anatomy

I was trying to draw a Bone Demon from my brother's D&D guide, but it turned into more of a study of human anatomy.  I'm really surprised and happy with how easy it was to draw the legs, even though the hips are too uneven and not quite right.  The curves and especially the calves and feet came out much better than I usually do, and I feel proud about it.

Proportionally, the legs are too long compared to the body, and the right hand is backwards, and the skull is bizarrely deformed.  I'll try to do better next time.  :)
