Visually appealing map. The borders are clear and connections are well-drawn. There are a variety of different sizes of bonus regions, making gameplay variable and interesting. As you're probably aware, the major issue with this map is the isolation of its southeastern portion. Another river connection or two between the Yin region and Mengzhanjiyi or Shigaoceng would alleviate this issue. One could say the same about the southwestern section of the map - that it can be held with only 4 territories in defense - but I think it likely that a player who controlled the entire southwest would already be steamrolling to victory.
