Actually I made about 50% of the picture myself, with some help from the South Park "Create a character" game. It's unique, so it's safe, just has a South Park style to it. I don't think there's a law out there that makes "style" illegal.
But really, does it look that unprofessional? I think it's pretty cool.
By the way, that shark on a unicycle thing didn't make a bit of sense. :-(
