After getting some feedback, I've decided to go with the "A Clockwork Orange" style cards for the upcoming 20th Anniversary Edition of Pettyland. I've also decided to increase the card size to 3"x3" (from the original 2"x2") after printing out the other prototypes and seeing how TINY they were. I must be over compensating for something.
I also redid the Peasant Burning illustration. I'm not used to working in such a small format, and I have to keep reminding myself to keep them simple. So, this version is simpler and reads better when printed out. Plus, it has a mushroom cloud of sorts, which was clearly missing from the last version.
