This is a non-commercial side project, and video is a short teaser, full video is still rendering.
I'm rendering it over night, and since it will be a fullHD 60 fps it will take a week or so to finish it.
@RolandB: I have ~15 mins/frame on dual xeon e5 2670 v0, and whole animation is rendered on 2x dual xeons and a pair of i7 machines. Noise level is set on 7% and denoising is quite high on 0,75. In my opinion animation doesn't have to be as clear as still image, hence these settings are not that high.
Thanks for your comments guys, final animation will be updated here!
