A lot of potential.
Though I have to admit, this submission is very good, there are some flaws which destroy lot of potential behind this great stuff.
I don't write reviews very often, but in this case I thought it would be useful to note some things which catched my eye.
First : The cuts are quite unnatural. Try adding some flow, faster scene changes going hand in hand. At the moment the whole movie loses a lot of correlation because of that.
Then there is also some problem with the animation. Often they're also quite unnatural, don't know, maybe this was your intent. In case it wasn't, try making them more fluid, so they make the impression of fitting in. You can see very often the mechanisms behind the animations, the separate shapes, it simply doesn't act like a movie as a whole. To describe it in a word : It's some kind of deadpan.
Also there is a lack of really good effects, for example some good fire. While you really do things like DOF and fast cameradrives through the landscape very well, things like explosions look quite "flash"y. I know, Flash isn't designed for that kind of effects, still I thought maybe this would be useful to you, so I mentioned it.
And finally the music. Same goes here. The cuts are quite spontaneous, and don't go well with the movie itself. Try to chose the music, so that movement on the screen fits with the musical background. Also i kinda disliked the musicchoice itself, it didn't really point out the plot, it was rather random imho.
To sum it up : This submission was really great, but it lacks the finishing touches. It doesn't make an consistent impression. Keep up this nice work, and try to do it better :)
4/5, 8/10
