Blue-Paint-Sea over on Deviant Art has created this really neat season two version of the Comic-Con poster from last year. There are a couple of characters missing, but for the most part everyone is present and accounted for.
I wonder if the upcoming Comic-Con will have a new official one? I can't wait to see what they do with MLP there outside of the contest mentioned earlier.
Anyway, check this poster out here, or use this link for the massive sized one (Warning: Old computers probably wont like this link!)
