I've changed the colour of the ocean and tried to give a bit of height/depth to it. It mostly looks like the islands are sitting on clouds, which, terrible, but I can't figure out a method of fixing that that I'm satisfied with. I've also begun defining the actual border of the map - the plan is to have an ornate(?) frame around it, which can be carried over into other maps for this world. I've also added a texture to the ocean, which is either too subtle or not subtle enough, I can't decide. Also, the thumbnails are really dark for some reason.
