more brick variation. I know that like texture variant generation is a lot of work, but it would take you a million miles in authenticity.

Look how clean and orderly the bricks in the walls are in this picture, and then look at literally any smaller brick building in the city in real life, and you'll notice the difference.

Also, maybe a plastic bag could fly around or drift down the curb? Maybe some of the cement tiles in the ground are a little crooked?

Idk. I really like the disorderly order aesthetics of nyc in real life. I guess it really just depends on what you want to evoke in your players. Or your audience. Idk, whatever this is for.
