Hi fellas!
During my participate in epic ILM Challenge on Artstation I got a pleasure to make tutorial for 2d artist magazine about matte paint technique in interior concept art.
Couple of sleepless nights and here it is:

I am very glad to present to you a tutorial where I share my workflow and some tricks (tips) that may help make your works more impressive.
This tutorial will be useful for those who want to create more realistic images using matte painting techniques and a few 3D programs such as 3d-coat and Keyshot which will help to save time.

Hope you like it!
