Quit good
Yeah it's good, but this is like, your tenth flash? Iwould've guessed your 2nd or 4th at least, by this time you should at least have some more experience (animating / length wise)...
Oh well guess some people learn at their own pase (like me and me english... XD)
But things you could looke out for; don't use motion tweens for fading in etc, but for special type of animations (color changing etc) or use shape hints, the motion of the body parts could be smoother (maybe use different symbols for upper and under arm / leg)
Try not to use to many bitmap thingys (like the referee or the walls)
Overal; Nice music, great quality and the drawings are quit good, not superb but good.
Cheers, keep learning ;) (visit the tutorial page once in a while)
