For now I am just posting the back design. Feedback is appreciated.
Also, what do people think of abstract face cards?
The back is OK, so far. Like Alex said, show us a bigger image.
As far as abstract faces - when done well, they're gorgeous. When done poorly, they're horrible. It really depends on the design. Look on the NDR at two Kickstarter projects, one completed (Vanda) and the other in progress (Lucent), both popular abstract decks. Then look at another KS project that's active (Simple) for a design only a mother could love.
When you really get down to it, unless you're making some highly realistic/photographic images, all decks have some degree of abstraction to them.
