Wow, that's looking pretty darn fine so far, I love it!
The only comments I can think of so far (besides can't wait to see it filled out and finished) is to watch out for the consistency - at the moment some of the heraldic symbols look pretty crisp and clean compared to the rest of the map. It can take a bit of work to move those into a consistent look and feel with the rest of the map.
Still, from what I see so far, it's looking pretty darn fine!
