It's a good start.
You've got a good start here, especially with the head, but with the body it seems you lost all sense of proportion compared to the head. A simple rule of thumb is that the chest is the length of two heads and the entire body is around eight heads tall--if I remember my ninth grade art lessons very well, that should be right.
If you look up some anatomy stuff and went back to the drawing board on this it would be much better!
