Yours looks good compared to most of the ones I saw - one was like 3 minutes (3 LONG minutes!) and used a lot of music for the background.Yes...it said no music was allowed. I wasn't even sure if I could use graphics, so that's why I didn't use any for mine, even though it would have been really easy to.
I've seen a few of the videos...but I'm kinda avoiding them b/c I don't want to be disappointed when I compare mine to other. You know, the I wish I would have done that...
Good luck with yours!
