This is the first rough of a map for a novel I'm almost ready to publish. When the map is done the book is ready. I'd love tips and advice.

I have a dotted line section that is a "mountain range" that from the east looking west is more like a ridge, and from the west looking east more like a mountain range. Any ideas on how to make that look good?

Help (and or examples) would be super appreciated. Also any other advice on my map. I want it to be great. But I am a noobie in the extreme.

Thanks!
