Could have been better
This could have been better, but don't get me wrong. You hae potential.
The most noticable thing was the slowness and choppyness of the movie. Things should be much MUCh smoother in a finished product. I watched it both on low and high quality as well, and there was no difference.
Other than that, just practice your animation a bit more to make more interesting fight scenes.
Good luck on your future movies.
