Well here's my try at it. My first or second time with GIMP. I know I screwed up on the mountains somewhere, but I've done that part 3 times and I can't look at it without glaring Same with the forests. I got really lazy at the text part, especially the title.
My big question is adding the rivers, you might notice some blue squigglys randomly placed behind a mountain, because I guess I added to the wrong layer. Could not find the one you mentioned. Paths-do they just take time to get used to? They seemed so strange to use...
The tutorial is great though, I think I'm going to try it again and hopefully get closer.
Also, like my gross font color/outline
