About the character:
Pro: The general drawings are good. Shadows on face are achieved pretty well. Face is cartoonish so it is a good point. Good desition to put 4 fingers only.
Against: Jersey neck is a little strange (has he neck?). And its lines thickness should be corrected homogenously. It has a bump in the trousers (front and back) that I don't like. He must looks thin as the general shape of the character.
