First question, can we set up USD only commission shops? Or do we have to offer services for in site currencies as well. Second question, is there an exact image limit? I saw the size limit and animation size limit but I didn't see an image count limit. Third question, and this is just a question out of curiosity, would pixel art sell here at all?

I'm mostly asking these questions before I set up shop because I don't want to do something against the rules at all, I'm not looking to get in trouble or anything like that I'm just looking to sell some art!
