Wow, now there's some nostalgia...
SOAD and stick fights. I'm in middle school all over again. Seriously though, it was a very well animated and choreographed flash. I honestly can't think of anything to suggest to improve it, so I suppose this isn't a very constructive review. Maybe Mushroomhead next time? Anything off of Savior Sorrow is usually pretty solid, although I guess technically Solitaire Unraveling was written as a fight song, so that might be more appropriate. Sorry I couldn't offer anything more useful, but I'm not really an expert on making flash, so I try not to tell other people how to do their job or hobby (jobby?) Also, happy late birthday!
