All I can say is:
Meh, I've seen worse.
I doesn't really look like a playing card design. It looks more like something you would put on a T-Shirt or a pair of shoes. To me, it doesn't have the right style for a deck of playing cards. That's sort of why I'm not the hugest fan of theory11 decks. The design are great, but they don't really look like cards. (I love the designs enough to use them though)
