Welcome to the Guild! I spent some time in Korea and really enjoyed it there. I think you'll find that this is the best place to be for mapping resources of all kinds. If you're new to mapping or just looking for new ways of doing things, I suggest looking at the quickstart guide to fantasy mapping. And for the style you're interested in, there is a great PDF in this thread <HERE>
Let us know when your game is finished or needs testers so we can check it out. I'm definately interested. Best of luck.
