O M G. I absolutely adore the richness of this masterpiece.
If anything, I would love to see a larger version (don't we always?), your textures are teasing me with how rich and deep they are. I so want to see closer. As a bumbling aspiring map maker who is now gathering his crayons to produce a map now, inspired!, I salute you.
I'll echo the comments of everyone else (border, water, continent map), plus mention that I absolutely love the textures. I also like how you did the roads and borders; they're there, but they don't distract from the rest of the map. Outstanding work!
