You're pretty decent at claymation ... Try cleaning up your clay a bit, I saw some like little speckles and imperfections. Also, make it a tonnnnnn longer, with a story...Not just a little animation with some music. Use what you've got and make a more meaningful.
hope you make even better flashs like this one

...But the song was so kick ass, I just sat there and listened to the whole thing.
