Horrid quality
The quality is as if you were recording a GBA screen with a video camera. I briefly caught in the credits that you apparently made this in Pivot or something. If possible, you should actually use Flash to make Flash animations... you could probably do a better job, keep the original quality, and reduce the file size.
This was too short and pretty pointless overall. They just sorta decided to fight out of nowhere and then he killed the other guy in one hit.
For sprite movies, you might also want to consider checking out Swish Max if not Flash... I dunno if that's free or whatever, but KNanakase uses that and he makes incredible sprite movies.
