Sorry I haven't been more active in figuring out what the new rules should be. I've been spending most of my time trying to take care of my health, and it's been really rough on me.
Right now I'm thinking opening up the bounty to any character, costume-variant or mash-up combination that hasn't been posted (and correctly identified) in the Good Cosplay thread yet. Maybe that's just me trying to cling to something of my orginal idea, but I dunno. Thinking clearly on the issue has not been easy.
Start working on the assumption that it's going to be at least that open, and if anyone wants to argue for a completely unlimited contest, feel free to propose what rules you think will work and why.
EDIT: Also, I'd like to say that I realize that real cosplay costumes are expensive. I thought this contest would be won by poster board and crayola markers. I don't know if this makes me seem less insane, or even crazier.
