That's actually where I was going with it. The details I add are mostly to the land. Adding white and a slight concavity to show the salt flats, dried rivers, cracked lands, dunes and bare mountains, etc. I might pull the town's label off or just mark it 'ruins'. I also have an idea for the lat/long lines that I'm working on. I think it's turning out nicely, but I'm not quite done with it yet.
