Hi cgtalkers
I tried to make a realistic and contemporary city with several tools for an animation project presented to the cop21 events.
This is a project for new electric vehicles, a better world 
C&C welcomed
Made with 3dsmax/vray/aftereffect and additional plug same ghosttown, evermotion and many custom building.

Holy Moly! That’s an impressive scene!!
I like the way you use atmospheric perspective effects for distinguishing foreground from background elements (the fog).
My first remark would be: I think the car is not so detailed in comparison to the surroundings. But maybe you don’t have much control over that.
I would add some little things like license plates. The cars look a bit too clean to me.
Thanks for your feedback
Indeed, the movement (car circulation) is a weak point, that’s true. (Car not detailed enough etc…)
