Not bad...in fact, pretty sweet!
What I believe you did was made an animated movie clip, then tweened it across the screen for the whole song. That's an original idea. But yeah I think it was well animated. If somebody draws something in flash I make sure the limbs and stuff are animated correctly, then they're likely to get an 8 in graphics. You were pretty much there, so I gave it a 7. Yeah. But overall(s), I think it was good. But you may want a weirdness warning. Just in case someone hates weird stuff./K
