That is one beautiful map. I'd definitely say you're going in the right direction! The highlight on the mountains feels a bit white/clean and gives them a very slight plastic-y look just where the highlights are. Gorgeous shapes, fantastic mountains. It's just that highlight. Also, along the coastlines in the water there's a lighter "boarder" with a rather hard cut-off line. That kinda looks out of place on such a well- (but not over-) blended map. Other than those two minor points, this is a gorgeous map. The colors are well-chosen and everything works together really well. The water looks really nice too; personally the light looks like a spotlight a bit, but the color you chose is great. Dunno what to suggest about that semi-spotlight-effect, since the colors and lighting are nice and the texture is just great. Probably just leave it alone, actually - it looks fine, it's really just my personal preference. Keep this up; love to see more.
