Thanks all, for the kind words. After doing some more writing for the campaign, I decided that the overland map needed a serious overhaul. As air travel will play a key role, it needed to be massively upscaled and I wanted to add more interest to the terrain. A barren wasteland doesn't have to be a boring one. Thought if I was going to go through the trouble of reworking the whole shebang I would experiment with a different style, outside of my comfort area, and try to learn something. I like what I've got going here so far, still need to add major roadways (suggestions?) and other things - like making the labels legible.
Much thanks to Tear for the Saderan tutorial! (oooh... THAT'S what layer masks are for.)
