Thanks Acrosome. I am familiar with using layers but not most of the other tools. I know there are some pretty good guides that I intend to work through. The thing I'm trying to get better at is 'fractalizing' my landforms. I already have pretty good coast shapes (from hand-drawn maps) and I'd like to convert them to digital and 'rough' the edges even more. I'm hopeful that once I get that where I want it, things will go smoothly from there.
