What should i add to this build to make it more realistic?

I’m currently working on a horror game, and i’ve made this build. I need some help on what to add.
(Keep in mind, i am not an professional builder. I made this using pbr textures using roblox studio, and not blender.)

Cool but I think that you should make more furniture or machines ,spilt open areas to small area or rooms , change light positions ,put something on the walls some blood or pictures and you can broke light plumps ,walls and windows

Wall trims and furniture

Also add more details to the lights
