Not bad...
...But could use some work.
I like the fight scene quite a bit. I have three pieces of advice:
1: Go with the flow of the music. Music heavily influences film, and the same applies with flash. There were a few parts that could have gone with the music better.
2: Allow more motion in the sprites. However, the sprites your using won't allow that too much, so perhaps different sprites or working on them on your own.
3: Follow up a little more. Sure, there's a battle scene...but why? I know that it's supposed to build suspense, but that didn't. It just made it feel like that was the end of the series completely.
Hope this helps! I may not have my own flash work to show, but film is what I do. Let me know if you have questions on anything!
