First off, welcome to the Guild!

Here are a quick three thoughts I've got about the map:

1. I really like the forest texture. A lot. You could tone down the bur on their edges, but apart from that, it's nice. The fields and desert are great, too.

2. Your brown areas - I assume they are mountains - look way too much like an autumn/drought version of your forest. They could use a more angular look, and there are plenty of tutorials and examples here to draw from.

3. The ocean, in my opinion, has waaaaay too much texture. It could really be toned down a few notches. Lower the opacity or blur the image.
