I liked it
But I just think you need to speed up alot of the action. For the space of someone to hit someone, its a lot quicker than we animators think. Just pop in any kungfu movie and get a stop watch, now time just how long it takes to through and hit a punch (that is with no special effects like slowing down time.)
It probably only takes half a second or just a second.
I'm just saying this because all the action you had in it, most of it seemed to be timed the same. If there was just a little bit more difference in the timing for all of the kicks and punches then I would have gladly given you a higher score.
Still, it was very entertaining and I loved the song. Asian Kungfu Generation rocks, and I think you did a wonderful job putting the action to the music.
