So starting from where i left off on the other image.
I added a few new objects (You may not notice it at all)
Added the call button for the elevator and a trash can.
But the main thing that changed was the light composure. Really tried making it look realistic with the light rays. Then repeatedly went back to change a few things like for 30 minutes or so. Really annoying.
But anyways tell me what you think of the render.

note: Scene will be available soon!
