I've heard that the creator doesn't like his images spread around unofficially in any form, though I've yet to find something confirming this. Still, I'd rather play it safe. He's a man in his mid 20s, blond, and specifically supposed to be very attractive (supposedly correlated with his high level of Charisma). He has no official eye color, due to the comic's style, but I'm inclined to go with blue. I'm poking around myself, but if anyone has any especially good suggestions, I'd like to hear it!
