As always thanks for the feedback... some changes:
• Japan was bugging me all along but I thought maybe it was just a result of my mild colorblindness. I've given Japan the blue, China the yellow, and swapped the orange and teal in S. Africa and Oceania to make it clear that Taiwan goes with Japan.
• Four boats, flying their colors.
• "Roughed up" some coastlines. Greece and Italy look a bit better now, as does that eastern peninsula in russia. More to come as things bug me.
Still do to... replace the tree roots.
