Really shouldn't even say anything, because this is WAY better than I can do :P but some comments anyway:
The animation was nice and clean, and the characters and setting were really creative. Very original :) .The angles were a bit awkward, and it seemed they were always directly from the side. Usually, I don't really notice something like that but during fighting scenes, angles have a big impact (or at least I think so), and they're harder to depict than talking scenes or something like that. Like some other people said, he was a little too overpowered. It would be more interesting and suspenseful if they were evenly matched, and you were wondering how the fight was going to turn out. However, since he was the strongest one, I guess that pretty much explains it :P Great work and great animation (awesome music, too). 100 times better than I could do xD
