Hello
That's a very nice work, especially the textures which are first-class.
You could try to improve the lighting.
First, change the default 0.3/0.7 balance that anim8or sets for ambient/diffuse. I personaly always start with no ambient and diffuse set to 1. This will greatly enhance contrast and give you darker shadows. Use also intensively bump mapping.
At last, play with the lights ! Here an example of what you could do with a different set of lights :
The first light is infinite, bluie, 70% dark and comes from the moon. The second one is yellow and just above the door, as yours. Ther's a third one behind the right corner, a spotlight that could come from a passing car.
Third, add some fog. Here, there's a 20% dark blue fog.
