The brick wall, yep I agree, also I don't like the repeating texture, I can deal with that on Photoshop.
I agree about the floor too, I'll just do some random tinkering.
DOF, good idea.
Contrast, possibly, again I'll tinker.
I've added some random roughness to the door fronts but don't want to over do it as that's their product.
I'll be back with another render.
Thanks guys 😃
