Are the colors contour based or are they indicative of different terrain, ie forest, mountain? Using the CC3 layer effects to get the gradient effects in the brown and green areas is nice. The color of the rivers does not quite match the rest of the pallete.
Is that the glow effect on your text? On the map I am working on I seem to be getting a 1 pixel outline of the text in the color of the background and then the glow. It ends up looking a little strange when zoomed out, especially if the background color does not match well with the text color.
I really like how clean the map looks, good work.
