Who would place lamposts on the path it’s self? Looks the worst in the second screenshot with them nearly right in the middle.
The first screenshot actually looked good with the overall lighting being pretty dark, but I can see where the detail is missing.
Like said, more detail into the buildings (Not just flat roofs), displacement terrain, more graffiti and the like.
Here’s the third screenshot if anyone wants it without clicking the link
I think you should experiment with more ways of lighting rather than lamp posts that look very linear.
You say something happened to the town, why not have vandalised lamp posts, possibly one flickering in order to bring attention to something, or have lights mounted onto buildings instead.
Also, small details like drains and what not.
Oh, bricks don’t break off like that in the third shot above (Look on the left).
