Good job.
I saw this a while ago before it had the music. Lemme just say that the music made it a lot better, but you still need to make it a bit more fast paced in order to keep people's attention piqued. I know timing can be hard to nail in flash, so just keep that in mind when you're touching up the rest of them. It's your only real weakness as far as I can tell. Another way to up the quility a bit would be to work on the sound, but that's more a problem of your equipment, rather than your skills, so I'd suggest you keep timing your main priority. Hope this helps a bit, and good luck!
