A real fun, real basic set of Classes!If you slipped these into a copy of the PSG with matching formatting they'd pass for official. That being said, the layout needs just a biiiit of a touch-up to avoid hard-to-read black-and-white text on top of black-and-white illustrations.
A fair point about the contrast. I knew it'd be a balancing act for readability versus art visibility. I'm trying to be cunning and double-dip on limited tri-fold space. And I expect results vary a bit by screen, printer (settings), preference etc.
Nonetheless feedback is great so I've uploaded a version with a little less transparency for the text boxes - grab a download and see if it satisfies a little more.
