The problem with your lighting is lack of mood. Everything is flat shades of grey. You need color to give atmosphere. Create bluish moonlight to display a cold calm empty environment, and maybe warmer colors coming from lanterns and inside buildings to show warmth and add contrast, if that's what you're aiming for. Shades of black everywhere is disgusting.

You also need to work on the ground textures. You could use vertex paint to blend your base ground texture with other more interesting textures that also tile. Such as worn dirt paths, green grassy areas, dead brown grassy areas, brick roads ect...
The topic is covered here for the unreal engine: http://udn.epicgames.com/Two/VertexB...gTutorial.html
The same thing can be done in Max: http://www.cgshelf.com/vertex_paint.php
And I'm sure it can be done in Maya, however I can't find a tutorial on it =/
