Started a new environment a couple weeks ago. I don't know how much progress posts I'll make before I finish but I thought I would show you the block out I have going on right now. You can see by looking at the white scale model on the floor that the scale is pretty big for an interior scene. The general idea though is that what you see here will be duplicated down a line following the floor.
I'm going off a concept by Jonathan Kirtz made for Warhammer. You can see the concept here.
