It's touching.
It would break my heart to find the world it knew mutilated like that.
The 2-D to 3-D transitions (for lack of my flash knowledge) could be better and the video's pace could slow down a bit, at least at the end.
I think that the flash was put together around a music (as in the music was chosen to be visually interpreted by a flash). I think the flash may've been a bit more effective the other way around: the flash should be outlined and music should be found to fit the flash.
It's good and I see potential. Keep going!
