Poor Peter. THIS IS WHY HE TURNED EVIL AND BETRAYED HIS FRIENDS! Because artists like you don't feel like drawing him.
It especially hurts his feelings whe good artists such as yourself decide he isn't worth drawing, and being left out of such amazing pictures as this one is really bad for his remaining on the lightside abilities.
I really do like this picture by the way. It is fantastic. Even without Peter (who I'm sure I wouldn't want to draw either, I was just teasing.)
