I think I'll be able to deliver exactly what you want with the levels, since I have already worked on multiple cyberpunk-like scenes in unity, in terms of both development and design.
Correct me if I'm wrong but i believe the images have the "low poly pack" from polygon in unity store right? I have some prior experience in working with that. I can already tell the few improvements we can do like, adding bloom etc.
Let me know if you are interested, I'll look forward to working with you!
