Wow, this is incredible. I can't imagine how much work went into this. I like the way you've done the mountains- it's very "atlas-y" in my opinion. And the place names- brilliant. I'm envious of that script you have. Any chance it's adaptable to Earth languages so I don't have to go through and make sure I'm not naming a city "pickled eggs" in Aramaic or something?

Siiiiiince you asked for critique, my biggest one might be that when place names overlap with trees, it's nearly impossible to read the names since the trees are so dark. Perhaps you could make the trees a little lighter, either throughout the map or just in the areas where the labels overlap? Or maybe just bolding the labels would help. It would be a crime to hide town names like Hpapkaneyauara and Senemnetulcesonet
