It is actually nice to see how this map evolves. Though i prefer the second version - the mountains are creating that really nice relief, and colour is just the right match - your third attempt is really great improvement comparing to the first map. Thinner coastline is a point, Better shadow on the mountains really bring them to life. The icons are in better quality and the lighter tone of the entrire map works better imo.

Well done and i am looking forward to see next version in 2019 !
