Nicely done, Everyman. Thanks for sharing.
A couple of small points to consider... some of the text is hard to read (I find the Cyan on blue quite difficult). Adding a slight glow, shadow or outline to the text would help offset it from the background and increase readability.
The river that forks might raise some hackles around here... in general, rivers don't diverge, they converge, unless they are in an unstable condition (like a delta).
Also, I don't know the scale of the map! Throw on a scale and a compass rose and you are well on your way!
