Hello, friends. I have created a new city map--an evolution of a style I've been developing.
I have also created a tutorial detailing how I created the map. It's a very big file and--because I am not a professional by any means--it's very poor, I'm afraid. But if you feel it could perhaps help you in your endeavors...
EDIT: The tutorial is posted in the "Tutorials/How-To" section of the forum index. Go there & you can download it!
