Obviously, you've paid good attention to the settings of light_environment (as suggested by the name of the map), and that looks great.

However, some of the texturing could benefit from some adjustment. In particular, the windows texture on the buildings do not seem to fit the exterior siding of these buildings. Furthermore, I think the texture for these exterior walls would look better if they have some other texture than these metallic sheet ones.

But it's definitely a good start.
