First off, great map.
I have looked through the map, here's what I found.
Small gap in brush. High Mid.
Another small gap in brush. Jail.
Weird transition in steps, I personally don't like it. Others might. Edit: Realized it's lighting, my bad.
Standing on barrel, you can see this.
Misaligned texture, I believe this is the only doorway.
Weird transition. Straight concrete to wood might look better.
Gap from pillar to roof. Slightly unnecessary to fix, just pointed out for polishing.
Misaligned Texture.
I feel like there should be a wall here.
Lighting glitch, I don't know if this is possible to fix.
Misaligned Texture.
Would look better if flush to wall. It would also look better if planks were single.
Looks weird, made a more realistic suggestion.
Transition would look better if you did the same like the brick to wood but from wood to concrete.
More realistic if single they were single planks.
Remove this wood.
Weird lighting glitch, might be worth recompiling with slightly different light angles.
Top of bricks should be aligned differently, suggestion shown in image.
