This is Ava, a character design I created for my junior year illustration class. She's a character I created for a childrens book series. Ava is a lonely orphan that lives in a New England Orphanage, and doesn't get along with the other children. She is constantly teased by the others for her large head and her only friends are the mice that also inhabit the Orphanage. What the other children don't know is that at night time, Ava and her mice friends sneak around and play tricks on them.....
