OMG that's not parchment that's Human SKIN!!!

Just kidding but when I zoomed in it did kind of look like skin of some sort.

I think you are making good progress. Keep up the good work. I was confused a bit by the mountains in the sea but then realized they were just the beginnings of land that had only been seen from a distance? You might add a slight change of tone for the land just to make those a bit easier to understand. I can also see why you might not want to change the style of the map by doing so and whatever you decide is fine by me.

Not having done any political border type stuff I will leave that to some of the experts around here. Carry on fellow desert dweller.
