This is good stuff, and I've got some suggestions.
This is your first run at NG, huh? Kickin' concept, slick story, and well done animation. I personally threw my 5 vote in for all around excellent animation, and it doesn't hurt to have a really damn good opener like you do for this movie.
One thing I noticed that you could look at would be throwing a few extra frames into animating the movement of the torso. The only spot in the entire movie that seemed a bit off to me was the movement of the torso during walking and running scenes. This little added extra oomph will be very much worth it in the special edition you're planning out.
All in all, some killer work, and a fine way of making your presence known here on NG. I'm eagerly awaiting your next flash.
