Check out these shader and post processing effects!

Before:

Just using a simple shader on the texture creates this.

After:

After depth of field, bloom and vignette/chromatic. What a difference! Now to add sun rays, “see through” windows and some other things. Oh! And the roof eventually.

Random Cool Effect:

Use the visualize checkbox on Depth of Field for this effect. Creates a pretty cool visual that I might use in the future.
