Thanks for the feedback! Here are some wires, changed a few things since this shot, mainly expanded the carpark/block at the back (the area with the ramp on bottom image) because when I started to think about it cars would find it difficult to park in there as it's too tight ![]()

Here is the dirt alpha that I'm using that you mention on the sidewalk in front of the main building. It's a floating plane and I use this all over the scene. I'm currently making a UV2 colour map so may not need them in the end. Not sure what makes you think it's green, it's mainly brown dirt but I do have a hint of green in there. I agree there is something not quite right about it though just can't figure out what it is, as you say it seems unnatural.
edit : actually, looking at it again, this alpha texture is more green than I remembered it!
