Here is a big project I've been working on the last few months, a fan Illustration/concept art of the anime "The Eccentric Family" (Uchouten Kazoku).
I did a more complex workflow, starting with a sketch, making a small blocking on 3ds max for perspective and the small buildings, I imported this blocking in Unreal Engine 4 to bake lights, place trees and create references for the final illustration, then I took several pictures from different angles in UE4, and after all that, I did my final painting in Photoshop with the chosen view and lighting.
