Great job, here's some thoughts
I gave you a five, and to save you a long spichel on how well done the movie is, I thought you might appreciate some constructive critisim too.
The animation of the characters were fairly choppy--if the character models were a bit more detailed, then this wouldn't be as evident. But I knew you purposely attempted to keep the character design simple--but that only makes the poor transitions between animated stances more evident.
Moreover, I the fight scene left something more to be desired. I never really feel as if the Superhero was in any danger--and would eventually win, which was slightly dissapointing because the villian was presented in a way that made him seem more human than the protagonist. Here we saw a man who had been defeated and would strive to any means necessary to achieve victory only to be shut down, once again, by a cocky young man. Storyline in a nutshell.
Still though, the style was good and it was a well executed film. You really did a good job and you're only bound to get better as you go. This will probably even get frontpage. ^^
