Looks really good, man! Only two things I can see that could be changed.

Firstly the border around the land is very thick - probably a personal thing, I just think it would look better skinnier. Secondly, the fact that the map is tilted on a very slight axis. It isn't that awkwardly shaped, so you could easily just rotate it to fit in, and have north be directly up.

Other than that, it's great for a simple atlas-type thing. Obviously if you wanted to go into detail you'd have to whack down forests and so on and so forth. Some sort of scale would be useful too, in the key on the right - [--------] = 50 miles or something.
