I'm starting up a D&D 4e campaign soon and I decided I wanted a continental scale map to give the players an idea of their place in the world. I'm not much of an artist, but 4 days ago I downloaded The Gimp and went about struggling with it. While looking for techniques I found the CG here and signed up.
Here's my first pass. It's probably got some river violations and mountain violations, but I think it'll do. I mostly used RobA's tutorials which taught me a heck of a lot about the Gimp.
