okay.. for your first one not bad
The drawing was not that good at all but not too bad.
No preloader no play button no stop.. very bad.
The idea is.. bad.
The music is ok but not too innovative.
It's not really funny and it's damn short.
More like a bad music video than a good flash movie.
But as you wrote it's your first animation (if that's right) I have to bow ;) Keep on and I'm sure you'll get big some day (Or you'll going down the water pipe *muahahaha.. cough*)
