Aren't some of these shots old? I was watching the progress of the map over at mapcore and I thought you already added concrete areas near all the doorways as well as paths?
Anyway, I would displace the grassy areas, but be careful where they intersect with the path. You can clearly see the triangles where the concrete and the grass meet. I'd raise the paths a few units so that it doesn't look so awkward.
The bridge looks better with the wood, but I still think it looks out of place. It doesn't fit in with the whole commerical complex type theme. The footbridge looks like something you'd see in a Japanese garden.
I'd round off the concrete in the second to last shot, the right angle looks awkward, considering the fence is meeting at a different angle.
The outside of the buildings could use some more props, like piping etc. I think that was mentioned at the mapcore, but it deserves to be emphasized again.
Anyway -- looking forward to seeing this progress. Do you have any layout shots?
