One thing I noticed...
When the movie ends and goes back to the beginning, the song still plays. So if you play the movie again, the song is overlapped with a new one. And so on. Besides that, you show promise, but I can't really say I get anything about the series from this (yes, I know it's a teaser).
Didn't get it at all!
And why did you put Star Fox's song?
I think you need to add some shading to your drawings and maybe fix the animation so it's smoother, and then re-submit
