The dead tree in front of the small house is made by, attaching a lot of basic twigs and scaling and rotating them to get the desired effect.

The houses on the extreme left and the one in the background are made up of a variation of all the parts.

This step is fundamental, together with modelling, to obtain the desired look. For the textures I've used 3DTotal's Total Textures CDs. The textures I chose were, some metal, bricks, wood and stone from v1, v3 and v14. I have also used some dirt maps from v5. I've combined the maps in Photoshop using layer opacity, the eraser tool, the clone stamp tool and the healing brush tool.

Here are some examples of what I did.

The same textures I've used to make the respective bump and specular maps. Each object is UVW mapped using the box mode. (except for the well, which I've used cylindrical mapping coordinates).
