A HUGE congrats to all the winners. As for feedback, the only thing that comes to mind that hasn't been brought up already is the need for a dedicated AMV room. Also, if more editors attend next year, maybe an editor's showcase or something similar.
Well, now that I've properly recovered from the con, I just wanna say this was an awesome contest. I think my only regret was not getting to meet with more editors, but that's my main regret with EVERY convention I go to.
