Falconius - Thank you, and yes, I completely agree with that quibble. I started off using the Fantastic Maps method of the pen tool in Photoshop, but it was making me insane, and was feeling like I'd never finish the map, so I decided to use FMs scatter brush method. It was a tad hard to control, but managed to dial it in a bit to get something I felt like I could live with. It actually was a lot worse the first 10 or 15 times I started doing them. I got it to where it is now and was like -- DONE!!
