I really like your style and the colours are very nice to look at.
I only have two details:
-Turning the map clock-wise would be a nice touch.
-While I'm no expert in hydrology, I believe the Salfarsee should somehow flow into the ocean; the geographical features surrounding it don't seem extreme enough to create a fully locked water body, and the rivers flowing into it should eventually cause an overflow (unless we're speaking of a sufficient deficit caused by evaporation, or some kind of endorheic river that drains through the underground).
Other than that, it is a lovely map that deserves reputation.
