I think that the different zoom level makes a huge difference. Now the roofs look good, and the texture on them just appears to be normal roof textures.
I don't have any problems with the bridges, I think that they are a pretty good representation of the bridge.
The roads still don't look quite right. You might want to think a little about varying their width, or smoothing out some of the right angles a bit. Roads are always a challenge though. It's hard to figure out just what to do with them
I like the adjustment to the lighting though, I think it brings out a lot of the detail.
