Not bad
Graphics: Well, the only reason I gave you a 6 is because this is a sprite movie... So honestly, just count it as a 10.
Style: The fighting was alright, but I bet if you spent a little more time on it (not just 2 hours) you can really improve it and make it more wild.
Sound: Overall, nice music but a bit low-quality. That may just be the songs themselves, so if that's the case, count this one as a 10.
Violence: In this flash animation, this one goes with Style, so just look at that.
Interactivity: N/A for this movie. (except the play button, but that doesn't count)
Humor: Well, most action-packed movies don't really have humor, so this is really N/A.
Overall: 8. This was entertaining to watch, and I did like it, so kudos to you. Again, just put a little more detail in the fighting sequences. Also (this is just a pet peeve for me) make sure your subtitles have good grammar and punctuation. Honestly, I hate it when high quality movies have mediocre subtitles, but fixing the problem should be a breeze.
You might've already heard of these animations, but check out the Mario Bros. Z series. Those are some great sprite movies and I'll bet that you could learn a lot from those.
