Hey
Even thought the courts appear as if were the product of a middle school art project, they have they own style and I like them!
I'd say keep the courts and continue that style throughout every card and you got yourself one cool personalized deck!
The back design looks a little too cut and paste and I personally would change it or at least alter the design a little.
Good luck
Thanks... I think... I'm trying to go with a borderless design as I do enjoy those, this was my first stab at doing the back and I did a mock up of it fanned and liked the way it looked (see attached). Though I am open to suggestions.
Reminds me of The Little Prince.
The backs are simple which isn't really bad since the courts aren't that complex either. You should make the back two-way though.
The courts look childish but they're not ugly. Like what Aptombstone said, they have their own style and you should keep them.
Overall, you seem to have a decent deck going for you.
I'll mess around with the back and see if I can change up the pattern slightly to make it work as a two way design, I didn't even think about the fact that it wasn't.
I'm glad you like the style, I'm calling it my "Doodle Dealers" which is why I'm going with the simple drawings. They also supposed to be people or things that are close to me. (The king is me and the queen is my wife by the way.)
