One thing - In this videotutorial I didnt't show how to create windows because it's verry simple process so don't kick 
Apologise for my english.

Scene textures


Shaders Settings



If you want you can also play with photoshop settings - for example try change those parametrs:

Image -> Adjust -> Shadow/Highlit
Shadow Amount = 39%
Highlits Amount = 0%

Thnx for your time.
