Maybe this island map will be done one day, after all? I've worked on this on and off for a LONG time, and it just never get prioritized. Sorry about that! Here is my latest progress. I've added some water, and the grid you have for the puzzle.
So what's left? Well, the background, the labels and some (or lots) of detail works. But not too much, Boiler Island doesn't have all that much detailing. I dread when I have to start on mapping/spike island!
