Character Design - Assignment 2: Antagonist

Front, profile, and back pose of an antagonistic character. This is the first in a series of three assignments in which we had to create an antagonist, protagonist, and comedy relief character. For my first, I chose to turn my pet rat Chippy (pictured below) into an antagonist.
Chippy was born with one eye and is a bit of a bully to our other rats, we actually have to keep him separate from the others because he is a grouchy old man and refuses to get along. :( He ADORES people though, and in reality is a super sweetheart and my favourite rattie!
