Nice job, I like the effort you put on colours on this one! A few comments as usual
- I'd grab the same colors for the key icons and the map icons. here, the key icons looks a little more pink than the red map icons.
- I'm not really convicted by the transparency of the areas labels, which make other elements and labels overlap them. In my opinion, you should better work on labels location to make it more readable.
- Improving the coastlines and the rivers would also probably turns it out better (need just a few work I think)
