It's a very pretty map, especially at lower detail. I think the major flaw with it is that there is too much detail on the full version (especially on the mountains). The lower third of the map by itself is spectacular (as is the left third). The middle field of mostly-mountains has too much curly detail for my visual system to process at once, which makes it appear to "crawl" as my eye wobbles around to try to look at individual pieces of the mountains. The monochrome version doesn't have as much detail and my eye doesn't have the same problems with it (and the cropped version with the brown mountains doesn't bother me, either) . I suspect that it's a contrast issue which stems from lack of white space.
