[Award Winner] Using GIMP to Create an Artistic Regional RPG Map

[cbridges392012]

Thank you for creating this tutorial, it's exactly what I was looking for as a new dm needing a map for my players, and a perfectionist who wants the tools to world build the right way

I've gone through the tutorial, as well as the revised version by wisemoon, and when I get to the sea creation portion, I'm running into trouble. This is the result I', getting:

My land is blue, the sea darker near shore than in the deeps, and when I try to add land colors, they blend with the blue. I can't figure out what I'm missing.

One thing I have noticed about both versions of the tutorial: the type of fill for a new layer is often not mentioned. Noobs (like me!) need to know.

Please help!
