The overall look of the map is superb, of course. That particular style you do is really unique; very sharp, really nice use of depth, the color scheme is a little mute, but still cool.
The only thing I have an issue with is the hills. At least that's what I think they are. I'm talking about those circle-shaped elements, with the strokes around them. I just can't seem to figure out what they are suppose to represent. Are the strokes suppose to indicate elevation? If so, they look sorta like big bulbs, not like the natural shape of the land. Given that all your other representations of depth, like the southern ravine and the Maw and all the mesas, look really stunning, I think those circles look out of place.
But really, literally all the rest looks sweet.
