So all walls suddenly become brick when the world ends?

So where have all the objects gone? They don't just magically disappear when everyone dies. I think you've taken the "emptyness" to the extreme. Rooms shouldn't be completely void of objects.
You want to creat a dark and dingy atmosphere but at the moment I'm not feeling it. It's too light and the rooms are too big and square. Lower your ambience, create a very light fog, find some trashy entities - (rubbish/broken glass/rubble) and decorate the environment.
In the second shot your boundary is too obvious, download the free model pack
model pack 36 and use the buildings in it to create a more realistic street. Also, if the world had suddenly died out, the streets would be littered with all sorts of junk - old cars, rusting benches, dead trees etc.
You could make a very atmospheric game if you just put more time into decorating it. At the moment it just looks bland.
