Sketchup 3d design of a modern building

This is a SketchUP work in my early days. I use SketchUP 6 and Vray to produce this general modelling of the house. It is not so detailed. After rendering I take the images in Photoshop and increase the contrast.
Overall-
Software used-Sketchup,Photoshop
Rendering engine-Vray
Time of rendering-1 minute.
