There's a certain cool factor to the designs, to be sure.
I think making the indices different from side to side is a mistake. Card players generally prefer a degree of uniformity to index designs in order to be quickly and easily understood, no thought processes required. Pick one design and go with it.
I also think that from what I'm seeing with the kings, there's not enough differentiation with the faces. For the "cyborg half", it's clear that all the faces were modeled from one face design. On the bottom, the Kings of Clubs and Spades are identical, and the King of Hearts is the same face minus the facial hair. The final "sin" is that all four kings are wearing exactly the same wardrobe.
I think your design would be more successful if you used standard courts for the "traditional" half and followed their variation when creating the top half. It could mean the difference between a so-so design and a great one.
If you have further questions, please note that I'm a consultant for playing card designers and one of my specialties is improving a deck's functionality. A designer can make a pretty deck, but with my help they can make a pretty damn good deck that people will use more often.
