Make more movie trailers. Please.
First of all, the fact that you did this for TOFA, is just amazing. The amount of time you were given for this was seemingly not long enough to produce anything as good as this.
The theme for TOFA round three "dividing by zero" seemed so hard to interprete in a flash, yet you made a trailer that makes me want to go see an actual movie.
Music: Very fitting. I can't say much more other than it helped the atmosphere of the trailer greatly.
Voice acting: You could replace the guy who does movie trailers. Your voice was nice an subdued for the action, and when the numbers were talking, their various plights were easier to imagine.
Without your voice acting this flash would have been a comedy, instead of an action/comedy.
Animation: Not AAA material, but since it is TOFA after all, it is understandable. It got the message across, and still retained its sense of seriousness, even though all the characters were just giant numbers.
My favourite line has got to be "release the primes!". That line had me (for once) laughing out loud.
Conclusion: Great flash. I think you should make more action flashes, because you show real talent in that area.
P.S If you made this into an episodic series, I'd be ecstatic.
