not bad
I really liked the animation.. like the bodies were drawn really well and the action was cool.. and that face thing added an interesting style. However, I bet w/ time and practice you could make your style a little bit cleaner.. maybe give the characters more natural movement and improve your backgrounds.
As for sound.. the techno fit well for the whole fighting scenario... but personally i thought the vocals within the music itself were pretty lame and took away from the effect, so i wasn't really diggin that particular song. But all in all i think it was pretty decent and shows a lot of potential
