Fix your Rivers.
And you did such a good job on your rivers on your other "first" map. I hate to write you up a citation, but the law is the law...
Eoinmorgan, you've got a couple of rivers on the south side of Vangaul that split downstream into two rivers going to the sea. This is geologically impossible. Forks occur when two rivers join into one - they do not fork downstream. A river will follow gravity to shortest way possible to reaching the sea.
A large slow moving muddy river often leave deposits of silt when it enters the ocean since the ocean doesn't continue the rivers flow. These deposites can cause the river to move its channel to better reaching the seas. This causes a delta to form. It technically is not forking downstream however - rivers never do that.
Also there is a river in Ossus the comes from the mountain and ends at a lake. Not that this is impossible, but you should have a river leaving the lake and going to the sea.
Other than that, things look fine...
