I would like to help you, but as I explained I cannot. If you think this is stupid you can only complain to Comedy Central.
I wanted to earn money with the pictures myself by including a shop with T-Shirts. But Comedy Central does not allow it. Even I am not allowed to use my own SP-Studio drawings for a shop. Believe me, I am sad about this as well

. But they have the power, they own the show.
Sometimes even if you create something you cannot do everything you want... this is the problem with fan art.
Things would be different if the pictures would not be based on South Park.
