You've got some good elements.
This isn't that good. You put zero effort into drawings and backgrounds.
Zero effort into original storyline or unique characters.
What you DO have, is Choreography. When it comes to animation itself, this is not bad! Lots of good kung fu action and camera angels, a bit overuse of the slow mo - matrix thing but otherwise the animation was good.
And the atmosphere you have set up at the end when the protagonist dies is pretty good too.
Seems like you have some decent animation skill. Put it together with some quality graphics, storyline and so on, and you could be pro.
