Thanks for sharing your design with us.
The art's not bad, but something's not right. Maybe I'm looking too close, but it looks like there's lots of little "jaggies" - pixelation - on some of the curves and angles, any line not perfectly horizontal or perpendicular. Perhaps a graphics program upgrade is in order?
I see that you're doing away with the art standard for the courts. Be aware that this will reduce the chances that a poker player will go for using the deck. They love their suicide Kings, one-eyed Jacks, etc. and know which ones are supposed to be which in a standard International deck.
The additional lines drawn through the center of the card are not too bad with the courts, but they're terrible with the spot cards - it's all too busy, lacking elegance and ease of use. On the courts, it actually looks reminiscent of a prison cell. Consider keeping the center circle clear of the "bars", as well as removing the outermost bar frame (the one that cuts into the indices). If you're dead set on keeping the outer bars, consider shrinking the bar pattern a little so it all fits inside of the border - only the indices should be outside if you want them to be easy to read. (Hint: indices should ALWAYS be easy to read.)
The whole bar motif on the faces just looks so cluttered. It's fine for the backs. Though now that I'm on that topic... Consider making a back with a simple white border all around the outer edge, then make your design with all-silver on one back, all-gold on another, to create an easy-to-distinguish "poker pair" of decks. If you insist on having the mixed metallics, use an all-white center for one deck and an all-black center for the other. The backs should be really simple to tell apart from each other, insuring that a card from one deck doesn't accidentally get stuck in the other deck.
Why on Earth would you so severely limit the number of decks made?
You have good artwork for the courts, the indices and the pips, but it all just looks so boxed in and cluttered with all those bars all over the place. Consider a simpler face design.
