RPG Map: The Commonweath (An Island nation)

[Legendsmith]

First post here. I'd nearly forgotten that I made an account a year ago, just for browsing.
But now, I've made a map, mostly following Butch Curry's Fantasy Cartography tutorial. It's my second attempt at mapping, so any critique is very welcome. As are any tips for my next attempt.
The map's for an RPG I'm running. GURPS is the system, for those curious about such things.

I was going for a watercolour, hand-drawn style. I understand that the map is quite distorted due to the paper's texture, that IS intentional. The player characters have an old, dusty map that hasn't been cared for. I am working on a cleaner, "newer" version; if they decide to replace it as the campaign progresses.
