This needed a LOT more work before being submitted
Firstly, the sounds didn't stay in sync with the graphics at all. You're clearly using nothing but event sounds, and your computer is slower than mine, so the movie raced ahead of the sound. Use stream for long sounds that need to stay in sync with the graphics. This was really hard to watch, as the sounds drifted behind the story, and often covered each other up.
Secondly, all your sound was in the left channel. Really annoying when watching with headphones.
Thirdly, your animation was, shall we say, lazy. Draw one version of each person or object, and move them around the screen. I might have forgiven that if it was funny and well done in other ways, but It was hard to enjoy the story with the sound going all wonky .
It was pretty original, that's all that saved you from getting a 1 on style. But the whole thing really needs to be re-vamped. Good luck on your next submission.
