You have a very good premise
The graphics are very impressive, BUT, there's no excuse for the filesize.
You may say "fuck it the filesize, only T1 people will see it", but, when you work with internet, you can score much more points if your media is both visually astounding AND occuips minimal space.
The whole file is 6.6 MB. That's AWAY too much for a short animation. When I d/l'ed it (using Getright), I didn't expected it to be so short due the massive file size. And I bet it isn't the MP3 file, since it sounds like a reasonable bitrate. Your vectors are away too complex (did you traced every animation frame straight from images?), and you can drop the file size a lot, without no quality loss, by doing some optimization. Check my profile and e-mail me, and I can help you getting your files much smaller.
Your perfect art-wise, but will get much better with extra tech acknowledge.
