Generally the guys who make those things don't take such an active interest in feedback, and the comments you'd get in the announcements section would be all from ten year olds who clicked the 'comment' button beneath the animation and only signed up to say "epic!!!!1!!111!21!". This thread'll probably get more the response you're after.
I think it's a much higher quality than a lot of the stuff that goes up on SP these days. It was fairly well animated and it kept me reasonably interested. It had a storyline that didn't revolve around a suicidal loner suddenly becoming immortal or something silly like that, but was just right for what this sort of thing needs. And no one had hair which is a plus.
The speech seemed a bit forced, if you know what I mean. They were professionally done, but it may have been better to go for slightly lower quality ones that fitted better. Or just much less. I think a lot of it could have been cut with no real loss.
There were a few bits of the animation that weren't fantastic. I only watched it once so I couldn't give much detail but I believe there were some physics issues on some jumps, and a lot of the movement was tweened which made it seem a bit unnatural. I understand why though, since a movie that long couldn't really be animated perfectly frame by frame. I suspect it won't be an issue for 99.5% of the people who watch it.
The music fitted nicely, as did most of the non-voice sound effects.
Overall then, it's really good and I can see you put a lot of effort into it. I enjoyed watching it. I hope you make more.
