This looks pretty good overall, but I'm gonna make ask some questions in my usual nit-picky way. Whether these questions are fair depends on how realistic you want your world to be.
Why no roads between Deorif/Brimington and Centras/Twandor?
The Fiume River seems to run from a swamp near the ocean, a considerable distance down to an entirely different body of water. What's the topography like, given that rivers flow downhill?
I assume that the Fiume has other tributaries. Some of these might be worth showing, especially if they're navigable.
