As a basic design, I believe it has some potentially. However, currently, for me, it lacks that WOW-factor, which we all look for in a back design. Moreover, I believe the back design could look better if there was a bit of darkening here and there, and maybe shadowing. The deck may also have better success if the back design, as well as the deck, had a theme. Just stating my opinions.
Oh, not to mention it reminds us of the Vortex deck.
