I think the first thing we should know to give you good feedback is in which time you want to settle it and how it is going on in this time.
Do you want to have a clean look like in mirrors edge, a "normal" look like now but in a futuristic environment or a end time environment like in fallout?
Iīll make some photos from a door around the corner (not now itīs to dark at this daytime ^^) there you can see how it looks when a door needs a bit of special magic to be opened or a kick
it has the profiles of shoes that hit it weeks ago and the dirt is fading away.
