It looks good so far!
Maybe adding some trash on the ground or some furniture or something to fill up some of the space would be good.
Also, yes, add textures.
Looks good. For the “No Escape” text, I would make the text color a bit brighter. Though I like how everything looks so far. Overall, it looks nice. Nice work!
Nice horror game!
First the details and lighting are awesome!!!
Second u should use realistic textures for more details and i see in a image some square buttons, i think best u can do circular buttons to make that more realistic
