This is the final images in 3 variations of lights setup.
I was really excited to work on it. The building has a very nice design. I liked almost all except the entrance, stairs and the public realm in the front of it. I designed some public realm facilities at the front to make the entrance and the whole building look more desirable and sophisticated. Also I designed a visible part of the interior because it would plays an important role in the dark scene, in my opinion. I used 3dsmax and corona render with all advantages of its post processing engine. Some slight touches in Photoshop were involved as well. I hope you like it. And Good luck!
