Well, after almost a week of business I was finally able to get back to this map and put the finishing touches on it (the WIP can be found here). This is a world map of Eriond, which is the basis of a homebrew campaign setting that I've been working on for several years (a link to the world setting info is given in my sig). This is also a sort of reworking and expanding of the first map that I ever made here at the Guild.
The map was made using GIMP and Wilbur, with a little Inkscape thrown in for the text work. I created the outline and height map in GIMP, generated the rivers and terrain in Wilbur, and then added the bum map, gradient map and border work in GIMP. I've long since lost track of how many hours I've poured into this, and to be honest, I'm still not satisfied with the final product. For one thing I'm not sure how I feel about the way the smaller country labels turned out. I was going for subtlety: I wanted them to blend into the landscape. Who knows, at some point in the future I may fiddle with it some more, but for now I've got so much else going on right now that I think I'm calling this done. As an aside, I had to reduce the size of the uploaded map, but you can download a full resolution copy at my deviant art account.
I've also included a map showing the global rotation of the planet below. Finally, thanks to everyone (especially Ascension and Diamond) for providing helpful tips and suggestions on how to improve the map.
