I agree with Max. My first thought when I saw this was actually "Oh, a map from the Wild West!" because of the font. As for the waves, maybe if you'd drawn a few out on the sea, as kind of a fade out, it would have worked a bit better. This way to me it seems a little like relief lines which makes me think the coastlines are mountains.

Sorry for the (too) late critique here, been busy, so I didn't have the time to post in the WIP.

Still, great map. Thumbs up!
