Concept Art - Pride

I'm designing a role-playing game called Sinful. It follows the story of a boy or girl who can see demons, apparitions that are spiritual manifestations of humans' sins. The child is told he or she must fight the demons, and the story is about the resulting "adventure" that ensues.

Each sin has five forms, and an accompanying color and animal; Pride is a purple bird, for example, and this picture is a rough sketch of what I expect its final form to be.

Wrath - Gluttony - Avarice - Envy - Acedia - Lust - Pride
