I really like the color scheme so far.
The coastal details are well...different, and aren't exactly to my taste, but hey, that's why we put these out here to see what everyone else thinks.
If I have any real criticisms, its that the majority of the islands are awfully 'round'. Maybe distort some of those that are close to the coast so that they somewhat mimic the coastline?
Looking forward to see hw this progresses.
