Two words: slow down!
The concept was okay, and the graphics and animation were also okay, but it was way too fast. I mean, 15 seconds for a movie that's 1MB in size? Not worth the time it took to download.
Your dialogue was passable but I only know what it says because I happen to be a fast reader. For the rest of the population out there, they have no clue whatsoever.
I gotta wonder, why is it 1MB in size anyway, when there's no background music at all? Some sound would have made it better to watch, and probably make you think a little bit more about how to pace out your movie.
