Yep incinerator without and incinerator.
Following what Raj said, maybe if you look at some pics of ruins to get an idea. First thing is rubble, vines and general debris. I see this in many maps, even my own like airport - too clean, too perfect. Take a look around you, and outside, everything's got marks, smears, cuts, dents, ridges, lines.
This isnt negative criticism, the map is a great concept, nice work!
