Constant

I was learning around with 3ds Max and eventually found something that I liked . I added some grungey brushing and some color in photoshop.

C&C are appreciated

I think the texture in the glass isn't really right for it, looks like it's for the ground? Nice idea though, I really like how it's constructed, it's like a city street.

What renderer did you settle on? Scanline or Mental Ray or...? Judging by your shader, is Phong the shader you started with? Lots of room on improvements as in lightning, focus point as well as shader.

Nice
It hsa a bit of an illusion look, to me atleast. I really like the mixture of textures. For some reason it reminded me of the Batman: The Dark Knight poster... probably because it looked a little like a city scape from birds eye view.
