It was alright.
Would have been better if you'd varied the song a little instead of singing the same chord over and over with different words (heck even just changing the ending so sometimes it ascended, sometimes descended, sometimes held the same tone). It gave the flash a very stale feeling -especially at the end.

The graphics are just ok, same for story, but the voice, sorry, it's hard to listen to it the whole movie, looks like you inhaled helium, and i can't support that voice, really.
You have to work again.

The ending was surprisingly profound.

Pretty good, I think the drawings could've been better and perhaps some more frame animations. The song has good lyrics and I think the voiced fitted well to the quirkiness of the animation. Try not to use the gradient tool so much (Like on Jupiter).
