Disregard my last post :P
Here is something i think you should add in the building tips
Focus points
I have made a pic for it
Notice how the white one makes you focus more on what is happening inside right?
What does the red light to? It makes you focus on the light. :o
And when you look outside doesn't the white lighted building look more inviting?
If you want to contact me more about an article about focus points, email me (check my profile?)
(if you want i could do a little thing on decals and what they should be like, or just check the forums on that one)
