This will probably be the next project I start. I wanted to do a big hatted witch character, but I didn't want to do some boring standard witch in a robe/dress thingy.
So, her back story is that she was created in order to wield a great power. The power was far too great for a human body to handle, so she was created as a puppet to channel it for her master. Something along those lines.
I want to do this in a sort of stylized way. Like lots of T&A and exaggerated proportions.
