I like the scene a lot.
Did you use modular elements with the pillars to construct the scene? Is it one mesh?
How did you build the UV maps?
How did you approach PBR? The emmisive mapping fits well, how did you construct the material for this?
These are questions I would have for you. Of course if you provide a download to showcase your work it would be well appreciated, and answer a lot of potential questions via example. Otherwise some discussion or tutorial would also be nice to share. Please let’s discuss and share our experiences with developing detailed environments. It will do nothing but improve all our art.
