White's land, black's ocean. I do eventually plan to make the map pretty, though I'm also hoping to have one in a topographic style where I can pick out individual mountains. Having tried that multiple times before I know I'm destined to failure, but you can't win if you don't try.
Trust me it only looks this detailed due to the scaling. When I zoom in all the way this is what it looks like at the currently most detailed spot
Eh, your coastlines are still more detailed than mine are. I've posted my map elsewhere in this thread, but I'll repost so you can see what I'm talking about (plus this is a slightly newer version with some added details, but also a few imperfections since editing isn't 100% done).

As you can see, my coastlines aren't nearly as detailed and elaborate as yours. I'm more of a big picture kinda guy, I suppose.
