I'm getting what looks like 14-18fps through youtube and I have a very, very fast connection, so that matches what everyone else is seeing I guess. 

If it was rendered at that framerate, consider adding an amount of motion blur as that can smooth things out

Mac gamma is different than PC gamma (pc is slightly darker) - just FYI

I think you are capturing the grime and "street" of the city surface while contrasting that with refined tech and aesthetic at higher altitudes (ala bladerunner).  You might consider stronger color and shade contrast but I really like how the green-glasses character emerges.  If I just saw the green glasses at first in pure black, and then the face emerging around the glasses as reflections of light hit his face - that'd be cool.

Looking forward to seeing your next piece.
