The shot above is WIP so let me explane;
Dirt: Dirt is probably the last Detail I add to a scene. Once a scene/corridor is finished and I have the right texture for it I will add dirt either to the Texture itself or by decals.
Orange Light: This should be like an emergency light you know. Yes the model is still missing, all my tries to create one ended up pretty ugly

By now, the scene improved already a bit, maybe I will post a Screenshot today if you guys want
