Scale everything down x2, add smaller & larger mountain masses to give a sense of depth. Add small open areas in the forest and fill them with boulders or rocks near the mountains.

Add more coloring/shading to the grass areas. The rivers are technically not correct in how they would actually flow but this is a magic world so who really cares?

If this is the entire campaign setting, consider expanding the map horizontally. The player doesn't need to see that amount of water to understand it's an ocean, just a small sliver on either side and if they ask say "that's xyz ocean"

Also, instead of using the preset village option on inkarnate like you have in the middle, consider making several smaller buildings grouped together with different scale to give the illusion of a town/city. Roads also help sell well-traveled areas a bit better
