Chairs look horrible. There’s something wrong with UV.
In the picture 1.2 the room is something wrong with the walls. looks like the wall has no thickness, it
s just a plane. Also you have problems with the ceiling. Why its black?
There are many elements there, you must have worked much modeling these objects. Good work!
Some things seem unfinished and highlighted in the scene, as the lack of thickness in some walls and wood texture in some objects, and the black ceiling too.
I like rom.1 (second image) in the first post, the kitchen and bathroom.
