To my understanding the movie portal isnt intended for animation tests. Its for the final project. But i may have missread the Terms of Use.
I tend to just use gifs for tests.. as to not clutter the movie portal.

But overall your animation needs some work.
Its stiff and clunky... doesnt seem to flow at all.
You seem to rely way too much on your flash tools.
I would really recomend getting ok at animating frame by frame tests before attempting to use these time saveing tools in flash.
Because you clearly seem to be useing those tools as a suplement for actual animation. And you arent really gonna get a good final product like that.

Im not saying never use the tools... just use them only when you need to.

Best of luck to you!
