Wow, this is really something, tryth. It's a shame that the song is kinda anti-climatic at the end, because I could watch motion like this for hours on loop. Real entrancing kinda stuff.
I'm curious, though, since I don't know the sources: how much of this is natural 3-D source footage and how much was your 3-D editing? Your best estimate, percentage-wise.
Anyway, whatever mistakes you might think are in this video are totally blind to my eyes, as I just see a pure flow of movement, totally unbroken. Amazing stuff, here. Fucking awsm job on your part, tryth.
EDIT: ha, Orwell beat me to the question. XD
