Wow. I really liked this. It had its own unique style that grabbed me from the very start and immediatelyhad me hooked. I'm not sure why you decided to redraw every frame, even still backgrounds, but it certainly gave the animation a strange naturalness that sits in exciting juxtaposition to the smooth edges, gradient fills and tweens most commonly found in flash animations.
I thought the sound was pretty great too, from the opening ambient sounds of rural life to the sudden monstrous drone that built and built as we saw the future flash by in a dionysian mess.
I would reccomend you try animating some parts with a lower frame rate. The animation needn't be so smooth for stiller movements (the ending for example should have been much slower paced, there were far too many cuts in too far short a time for the viewer to really see what was going on).
Definitely an interesting animation, keep it up!
