Maps like this make me want to sit behind the cartographer every step of the way and just watch. Simply excelled. I read in the original Finished Map thread that you used some of Tom Patterson (cartography God, we're not worthy we're not worthy)'s shaded relief maps, coupled with a bevel/emboss to create that shading effect. You should consider writing a tutorial for this effect, as I for one would love to see the steps in the process. The final effect is brilliant.
