Okay, cool deal. I'm assuming you mean no glow at all, including on the nation names. I was planning on doing a ton more naming and switching fonts around and whatnot anyway, so this will be a good opportunity for that.
I've been looking at the WIP Cora thread, and the map style seems similar to this one in a lot of ways, and he's using what looks like a bit of darkening at the edge of his land area to indicate the transition to water. Would that work at all here?
Oh, and I have a version of the map with hand-drawn mountains I found here on the boards. I'm working on good-looking placement, but even at this stage the image pipe I made out of the mountains has done a cool job.
