Since I'm still new on the map-making scene, all I could say is its beautiful.
If they didn't say that it looks like Greece and Turkey I wouldn't have ever noticed (I didn't really focused too much on the Mediterranean whenever I look at a map, plus I didn't look at your map in inverted colors, so there's that xD)

Either way, I hope I'd get to see your self-made coastline in the near future.
And if you don't mind my asking, what program do you use?
