When I saw this map, I immediatley thought of the Ascension tutorial. I'd done one myself called Paragonia, but this one gives me some ideas. It's a great style but requires you to come up with a whole lot of names to keep the faith. I like the sublety of this one. For one thing, I think the lack of wave lines is an improvement. I'm also wondering if you decision to not follow the curves of the rivers with the labels is a plus or a minus. Now I'm tempted to do another though. Great job.
