I tried to push the line of action on the third pig. Not sure how succesful i was with the new pose, but i figured i'd give it a shot.
The angle on the nose of the mouse is off. His head is tilted further backwards. I really tried concentrating on the line of action and the shapes on this one.
This mickey drawing is a doozy. This is probably my 20th stab at it, and i'm not satisfied.
