I remember your early versions with the different grill work.... I like this new version except for the flat red brick things on the walls. It makes your wonderful 3d model now look like a low budget broadway stage set (if you know what I mean) It looks like things just painted on the walls..... I suggest that you run some simple pipes and conduits around the walls and possibly a cluster of them coming down from ceiling to floor. Pipes will be easy to model and texture..... Try a steel one, a copper one and a large black corregated one (like automotive wire harness) Possibly bright orange or the black and yellow "warning" type to compliment your floors. For wall art.... how about radiation or bio hazzard symbols....... Just my two cents..... I'd like to see it when you're done.... Much of my work is sci-fi so I can see all kinds of uses for it.... good job
