>>7645738 (OP)I like some of his work. Played a couple sessions of RPGs with him on G+ in the past, he is a cool dude. Probably some kind of undiagnosed autistic from how rigid he is with standards of justice and conduct. I disagree with him on a lot of stuff but I respect the process he uses to come to his conclusions.
Anyway, a good amount of his artwork is a bit ugly to me. I'm not really a fan of caricatures and he tends to emphasize faces in that way. But that's my personal taste, not really a "it's bad" statement. I do like the more maximalist look overall, and some of his more abstract or game-related pieces, picrel, are the kinds of things I can stare at for a good while to examine all the little details. The Vornheim book is also proof the dude knows how to design shit in a very usable/tactile way, which is an excellent mindset to have.
I can't really say anything bad about his art other than that it's definitely niche which makes it "difficult". Either you like the more punk busy-looking game art, or you like the pseudoerotic caricature stuff he does for fine arts, or you don't like his work. And its 100% not going to fit as a decoration in every room due to the high contrast and saturation.
