Ok, after days of grabbing pieces of mountains and fitting them in place like a jigsaw puzzle, I think I'm happy with this. I had been trying to blend styles a little more into something that didn't look quite so obviously like it was copying Asc's atlas style, but my skill level doesn't seem to be there quite yet, lol. So I ended up essentially with the atlas style, but I kept the ocean hybrid from the previous version, and the cut-in rivers, and modified the color palette a bit.

On to placing borders, cities, etc., but C&C are always appreciated and I'm not getting rid of my layers, so I can make adjustments as needed.
