Ok, listen, you want helpful tips? I have one for you: ANIMATE. What you submitted was a sequence of, I'd say, 4, maybe 5 frames altering and a motion tween. The graphics were... come on, I mean, be honest, aren't you surprised too that this actually passed judgement?
Let's get to the sound. If you go to Flash's publish settings you can modify both the event and stream's frequency, as well as setting the sound to either Stereo or Mono. Set it to Stereo, and adjust the quality and frequency to whatever you like. Just... not this.
The voice acting, you just need to practice. And get a good microphone. Don't voice act if you don't have the chance to get decent sound quality.
I'd like to specify that, while all this comes from a sprite animator, it also comes from a person that is INTO animating, so I do know what I'm talking about.
And one... last... thing... THIS IS FREAKIN' MADNESS DAY! Your "movie" has nothing to do with Madness (except for the characters, obviously).
Peace, and happy Madness Day. Man, the words "Peace" and "Madness Day" do not fit together. xD
