I added a crack along the front of the garage, giving it a deteriorating feel, and emphasizing the need for the supporting beams in front.

I don't like how the garage texture is different from the tower texture.

I readjusted the tower texture, and now in the process of making the walls look more believable by adding details like water stains and crumbling bricks.  At the moment the texture is too repetitive.

This is a good example of a modeled environment. Similar to mine it required a lot of smaller detailing to make it more realistic. The staining, rust and broken bricks effectively bring the scene to life.

Added detailing to the roof.
