I really like the red in the background on the back design; it blends well with the drawn image and the shading.
If only you had liked it about eleven months sooner! The KS campaign for this deck closed July of last year. Christian was being very ambitious, looking to make the deck not only in two colors, but also from two companies - a total of four decks in a single project. An experience designer with a following can pull that off, but Christian couldn't.
There should be a topic about this deck in the Playing Card Plethora - when a project finally gets off the drawing board and launches on KS, we move the conversation to there. Ah, just found it!
