You should tweak the decks a bit - the "q" for Queen looks a little too much like a "9." You might argue otherwise, but tell me that after your third glass or wine or fourth beer of the night over a friendly game of cards...
Spots/pips would make a difference, but your design doesn't have them, so people are counting on the indices for card identification more than they normally would, which is a lot to begin with.
Congratulations on reaching your goal! Bear in mind, MPC does good work for printing, better now than in even the recent past, but they recently switched to a laser cutter instead of using a metal die cutter. The card edges are completely flat and smooth, unlike the beveled edge of a die-cut card, making them impossible to weave or faro shuffle. A minor issue to Joe Cardplayer, a big deal to poker aficionados, magicians and some collectors. But it shouldn't be an issue for this deck - it's more of a novelty deck and/or an art/design deck, so performance issues like those aren't as critical. In simpler terms, more people will buy it because they think it looks cool than because they want to play a hot game of poker or practice some sleight of hand.
