no need to apologize...
Dude you didn't need to apologize or make any excuses for this. It was really good stuff! Though I kinda feel the reverse of the other guy. I never really liked that song much (unpleasant experiences back in school...leave it at that). But your animation is terrific! It kept up with the music, ranged in detail (often just right for the pace of each scene), and the motion was fluid. You really are a talented animator, man. And while I'm not a fan of the music you used, I AM looking toward to seeing your future flashes.
Nice job! ^-^
