One suggestion: The cars and people are looking really nice, but I think the buildings need to be dirtier. They get wind and rain assaulting them, they get pidgeons crapping on them, they get trucks blowing soot at them... a little "texture splatting" of mess textures onto some of the buildings would make them look a lot more realistic, I think.

(Also, it looks like the brickwork on the far building in the second picture is moireing a bit - is that just an artifact of you shrinking the image down?)

Yes, the artifacts in the second picture are just because it's such a high res texture I'm doing a tex2dbias inside the shader to keep things sharp. When running at resolutions above 1024x768 it's not an issue. I took these screens @ that low resolution.

I have a detail/dirt map applied to all buildings, but I know what you mean.

I'm doing a second batch of city artwork, the second set will include more of a grungy look to it...combined w/ these buildings it should allow any type of setting to be simulated. Also included in the second artwork pass is a 3-lane 1 way roads, and elevated trains.

Thanks for comment.
