Quick painting I did in Photoshop, painted over a 3D level design blockout made by Antoine Tarkowski in Unreal to find the right mood and general feeling of the scene.
I wanted to stay as simple as possible using the right level of details to keep it clear and effective. I also forced myself to work only a day on it (maybe 5 or 6 hours I would say) to not get stuck into unnecessary details.
