Some cool stuff.
I like your art style, and this was indeed cool looking. No doubt it took you some time, and you should damn sure be proud.
On the other hand, there are also some setbacks to this. For one thing, I didn't really feel this song fit for this fight scene. I suppose I didn't pay much attention to the lyrics but it sounded more like he was singing about a woman or something and that doesn't really tie in. The music itself seemed a little too slow and not intense enough to be fight music. Voices, and this is a lesson I learned myself, voices will improve your score. Use voices. Another thing, you did seem to take some "animation shortcuts". I got to see a lot of them running or jumping at each other, but as far as blocking or trading blows there wasn't as much as there should have been. Flashes of white light and stuff don't really do a fight scene justice. Take the time to animate even just 5 seconds of close quarters combat here and there and it will come out looking cooler, I promise.
Lastly, the thing that turned me off of this flash the most was your authors comments. I'm willing to believe that you did this all on paper at one point, yes, but the end result showed no sign of pencil drawing. You traced over all of it with flash, so essentially it was done in flash. It's cool that you drew it on paper first, and you can mention that as a cool side note, but don't make it sound like we OWE you a higher score just cause you drew it on paper. To be honest I think you could have done the same thing (and probably in less time) if you had just skipped the paper part and done it all in flash to begin with. When you tell us about how you had to scan all the pages and such, it makes it sound like you're trying to get people to vote higher than you deserve because they feel sorry for you because you had to go through all that work. You chose to do it the long way, for better or worse, so you don't really deserve sympathy. And to color it you ended up tracing everything anyway.
But like I said, this is a good piece and you did take a good bit of time on it. Keep at it and you'll keep improving. I enjoyed it and hope to see more from you in the future.
