Great, but not Amazing...
What some of the reviewers are trying to say is that it's just fighting. And fighting without purpose or meaning feels empty. Even in Fight Club they had a purpose. The animation was great, the graphics, the loose control of the camera at the beginning was awesome.
It feels incomplete because it's not a story, it's the scene we see after the two characters can't resolve their differences and then decide to battle it out. It's a great scene. You could do something with the two human kids, since the shots go back to them a few times. Make a story between them. However this might be counter-productive since your style shows multiple fights, multiple characters, and multiple locations.
It was entertaining to watch, but became too long at about midpoint. Good luck with future projects! And great job to the animators!
