Here's an update on the alleyway environment. I had my friend Kazz give me a quick lighting direction to remove alot of the straight edge lines on the roof which in return breaks up the shadows on the ground so the alley doesnt look like sharp lines all over the place. Added a little bit more dirt on the walls and may consider adding one more dirt overlay to dirty up those in betweens of the bricks.

Also in his sketch he added some volumetric lighting to break up the scene and to add a good contrast, so I added some volumetetric lighting in post.
