Your model is excellent. I love it. It's simple, it looks good, and contrary to what others said, you actually have a pretty innovative business model with the possibility to sell crowdsourced designs. But if I were you, I'd make it more interesting for graphics guys. The real innovation would be to do a 70-30 cut like for iPhone apps. If it worked economically, even if it merely covered your costs, it would attract much better designers and many more buyers that would also buy your own designs on which you could make more profit. You're solving a real problem here: geek decoration. Be more ambitious about it!
