Here is what I think to be an upgrade from the last render. I'm sorry for the disturbance. I just wanna make sure the shadow displays correctly and the material textures too and the individual intensity of light on all sides whether or not they represent how light placed like that would be represented.
And... What do you think about the wall posters? Do they look too separated from the scene or are they okay that way? If they are not okay, I think I'd take a high res uv snapshot and embed them with the brick texture before importing back again. What do y'all think?
I did some poking around and the main culprit is the lack of linear lighting. Once that's set up, lighting is less of a hit and miss hassle. You'll need less lights and "trickery". Just turning on color management and replacing the spotlights with physical (area) lights helped a lot. The rest of it is just color grading and effects in post, better render times and more flexibility.
