I really like your textures! They look very detailed and seem to map nicely at the scale you're working at. It struck me that this may be the interior view of an abandoned plant, and that theres a big hole in the roof that they cut to remove machinery. You see that in a lot of actual photographs of such places. Many of these places also have huge gaping holes in the floors too. Oh, and I love the old "washcloth", that's an excellent detail!
