Not the best design that I have worked on, but I tried my best to make it look pretty. C/C are welcome. Thanks. 
very nice job. windows look a little too bright for me though.
Agree about the windows. Also the bldg appears to float. Needs more shadow on the ground.
dark area are too dark, your ground is great!
It’s a photo or other?
Thank you for all your comments. Only the building is rendered. The rest of the scene are sampled from different photographs.
Here is what comes staright out of Max and Vray.
you could give it some added realism by making cloud shadows on the ground/building. i see from the background it’s a cloudy day.
did you mean…
how to make a ‘not so beautiful’ building to a good rendering?
I guess increasing the realistic feeling of the surrounding environment would do a little help.
at least you can make it looked like a photo.

Man, it’s already very good! Cash this baby and keep the extra dedication for something worthy!
