Your last render looks great.
A few crits. IMO, the banners are blowing in the wind a bit too much. But that’s just me. Perhaps they would look better toned down. :shrug:
Also, isn’t the flaw infinite? At least that’s what I remember from the book. Right now it seems to end /begin with the second building from the left.
One more. To me the city kind of gets lost with the background. Sort of blends in too much. Maybe you can try adding brighter lights or perhaps some reflective hot spots might do the job.
Looking forward to seeing what you come up with next. Patricia?
