Hmmm, reminded me of a few things.
Well, to begin, the explosions, fire, and other fx looked similar to the old Bionicle MNOLG episodes. The running animations etc, not smooth, but good enough to move the plot along.
A word of advice: These are intelligent beings are they not? I would try and vocalize the sfx a little. Not actually talk, but make each one like they are saying something rather than just *insert bear growl here*. I know you spend a lot of time on animation, but sound effects are important too. The visual isn;t everything. But over all, I would say you did an EXCELLENT job. KUTGW.
