OMG, this looks like a hell lot of work done! And IMO it looks very impressive. What I don't like is the background music, this very low background noise in it is making it unpleasant. Perhaps something less distracting could work better. Oh, and I would love to see some form of narration, maybe a comic book-like narration, but still. Perhaps a minimal plot with a character going through all the stuff we see would not hurt. The information is very intensive, a lot in one place. Maybe it's a good thing, but I guess it would be more informative if it was prolonged but had fewer elements at each period of time so that we can actually perceive everything that's going on there.
