Dragon Ball Z, soccer style!
That was pretty good! Perhaps a little heavy on the file size, but the movie was worth it! I like your Japanese style in your animation. Like how the soccer ball sounds like a Kameameha (or however you spell) being fired off. Not to mention you have good potential as an artist with human figures. They were a little blocky, but not much of a complaint here as you didn't resort to stick figures as other first-timers do.
I reccomend though that you don't say this was your first movie in the author's comments. This creates the reaction in many NG voters that this movie is blammable crap with uncompressed music, and they'll blam it right away before seeing the first second of the movie. If this movie gets blammed, I reccomend you resubmit it with compressed music if possible. It should get a much higher score.
