Oooh, I love it! I really like how the elements fade into the background. Reminds me of the good old PC game manual maps that I used to enjoy so much. You, good sir, get some rep right this moment.
Only two things I'd change:
-The scale seems too sharp in comparison with the rest of the map. Perhaps smudging it a bit or using a less precise font would make it look more in line with the rest.
-Some of the names in red are a bit hard to read, such as the one left of the Crystal Cavern.
Other than that, a fine piece indeed!
