Rendered in Cycles at 512 samples with the denoiser. The main things I’m looking at doing now are adding rails and decorations, fixing the displacement on the bricks (it’s warping the edge of the window a little bit), and fixing the lighting. The lighting is a lot better than the first render I did (this is the third) but I still think it could be improved.
I’m using Filmic with and HDRi set to a strength of 200. I have the max light bounces turned down to 4, with Blender Guru’s glass shader and portals over the windows (which is probably redundant because of the node setup anyway). Anything else I could do to improve?
EDIT: I figured I should also throw in my reference image:
