did you draw your avatar, raikov? you're a very good artist by the way 80
i can't see anything structurally wrong apart from what ram said.
chisuukei, and thank you very much v;
I really like the character design of that pic you linked me :D the only things I can see are what's already been said, about the mouth too low, and the lower leg being a bit thin. I also think that maybe on the arm on (our) right, the line at the elbow showing the bend of the arm is maybe too long, for the position of the hand - when I put my arm in that position, the line didn't seem to go quite so far across.
I cannot see your drawings OAO
