Hey that's looking great so far!. The detail in the mountains turned out better on your map then they did in mine. I kinda like the squiggly rivers myself. Course if you're not satisfied with them, there are a few scripts and plug-ins for GIMP that RobA and others have made floating around the site somewhere that are particularly helpful for rivers (do a search for: "stroke path with taper," "Tapered straight path," "Fractalize Path," and "Smooth Path" if your interested). Yeah forests are sort of a must, but there's always plenty of time for that later. Your off to a good start though.

Cheers,
