Night Rendering-retail/residential

[mr. a]

HI,

Attached is an image I have been working on, using only standard lights in max. Question: I would like the building in the background to look lively, llike there are various rooms with lights on /off with slightly different hues. I would also like the illuminated windows to have some life/detail to them (depth) rather than just being solid colors on a solid surface.

 

Any suggestion on how to accomplish this? Do I actually have to build various rooms? I would rather do it with maps- know of any good sources for rooms at night?

 

C&Cs welcome.
