Looks nice abemore, only I noticed something funny about his eyes, they\'re too far up in his face. Eyes are always in the middle the head (vertically, erm how do i put this, they\'re equally far from the chin as the top of the head). They eyes in your drawing are over 2/3rd from the bottom. And his neck is kinda long and thin.
For the rest it looks very good, and as far as I can tell, it is anatomically more correct than the chick you drew. Nice improvement, keep it up. :]
