Very well done! You know your tools! Only thing I’d change: I’d remove the white tint in the glass modules. This is usually not the case on real glass elements.
What program is used?
Uso Sketchup e Enscape =D
Ive been having problems with enscape putting the white tint into the glass on its own - assuming its a light/sun reflection.Its a real pain to get rid of unless making the glass completely transparent. Darkening the glass or even putting a color overlay on it does not resolve the problem.
Could you kindly send me a screenshot of that behavior, alongside the material settings for the glass at hand? That would be great. 
But that’s exactly how a regular glass material should be setup 
Unless it’s some special kind of (frosted) glass opacity should be set to 0% for realistic results (and refractive index should be ~1.5).
look at last picture, z4.jpg
floor under the car should be dark right ? because of shadows of the light above the car
and the car in the left little going up…
