I really like the design of the Beemer. I think if you kept working on that it would be a nice design.
Lol thanks... Yeah... Copyright issues~ they're for practice only.
Well, nothing's stopping you from replacing that iconic blue-and-white with something like a speedometer...or a spare tire, or a steering wheel. You could really make a cool car-themed deck with that back. It would be fun seeing court cards dressed in racing gear, either old-time or modern (or perhaps in-between, maybe from the '60s, like something from an old Steve McQueen film). The joker could wave a checkered flag - and the reveal joker's flag can have the forced card hidden in the checker pattern! You could make it in assorted colors reminiscent of classic car colors. Maybe make a version with silver-inked chrome.
You could really run with this. Or drive!
