RR... I really am liking your cards and the font is growing on me.
The only very minor critique I have of them right now is the size of the letters/numbers (which I love) interferes with the suit in the background, especially at the top of the number.
Unlike mel, I like seeing the suits, but I wonder if this could be done in a more subtle way...? Like, maybe lose the background image and put the suit in the top, like how you have the small number, either next to it or below it or across from it - it would depends on how it looks in 4 card games like Omaha, I guess.
Just a thought.
Edit: Actually, I just noticed that the size of the 2d looks pretty good... the other numbers all appear larger?
