Nice!
Rather simple graphics but since it was your own work and put together in fine animation with a decent movie length, I can't tell you to do any better! Good Job! But to my personal opinion, I think you should probably use a different or better music. I wouldn't know what is better though, because there are a gazillion songs to choose out there!
The bottom line, however, is that you put a really nice effort into this. Keep it Up!
