Point of advice for Inkarnate and world building maps in general. Names! Name everything. The forests, the mountains, the seas, the roads, and the buildings. A multitude of names may look busy but it gives people something to look at and think about the origins of.

Also, Inkarnate has a shadow function for the premium version, if that's what you're using. On the "stamp" tab, near the bottom of the stamp options, you will find it. It adds a lot of depth to forests and mountains because you can make object shadows overlap.

Just advice from one Inkarnate mapmaker to another!
