I worked a bit more on this and think it quite handsome and striking. I didn't like the way my previous version highlighted the ocean hexes. In this version they are more subtile carved into an old samurai cloth pattern that I found. To soften the costline, I've added a water treatment. Cities now are highlighted white. I developed the pieces a bit more using a more relistic rendering of the bits. Samurai and Ronin pieces have samurai emblems on them. Overall, I'm liking this very much at the moment. the board probably needs one more simple decorative detail, but I don't know what that is at the moment. The samurai cloth pattern in the background adds pleasing texture without taking away from game play, which is very important.
