ok,here it goes *clears throat*
1 Your construction was a bit off(work more on your sticks,but you're doing good)
2.Your sticks had less movements(like in the use of less frames,try using more frames even thought it will wobble,work on it)
3.You over-used the grunt sounds(they are to be used when applying strong hits or attacks or more force,not multiple hits)
4.Try setting your sounds to stream(especially songs *or simply add a stop script to the end of an anim*)
Here: stopAllSounds(); <-----stops sounds
stop(); <-----stops anim
5.Practice on particles(cause you'll need them for slow-mo)
6.Use your sounds well and don't over-use them :D
You really have a lot to work on.Hope this helped,anyways good job done *thumbs up*
