Good stick animation, but...
watch out with the sound! There are these strong popping sounds during the punches and kicks. If you were trying to convey a sense of impact with those sound effects... well... you didn't. Take that into account in the future.
Other than that the animation was fluid and creative.
P.S. I'm certain that it has nothing to do with my speakers. I tried with both speakers and headphones. I also saw other movies before, and this popping didn't happen. It's your flash.
