Interesting deck, brother.
I like the pips you've done, but I'm kind of inclined to think that you're limiting yourself to something of a niche market with the court card designs.
On the plus side, the court cards are very unique... but on the flip side, they are so unique that without the K, Q, or J letters in the two corners, it's close to impossible for somebody seeing the deck for the first time to know exactly what court card it is. That may in turn reduce the appeal to those who buy decks for playing card games.
That's just my two cents though.
