I showed this post to a friend from Brazil from my RPG group, the group's artist, he really liked the Lurkers history and decided to make a drawing. I'm sharing his art.

His Instagram is @luisoctavionb for those who want to know a little more about his drawings.

And... another possibility is to use two Lands sheets - both with inner edge fade and the lighter one - beach if placed below another more yellowish, greenish, rocky, etc. When you open this file you will see in the sheets a new sheet called Land Beach -------.

I've been thinking about your map and the beach. If you want an even closer or more local map you can directly use the marine dungeon as the base of your map, working with the Edge Fade Inner effect on the land and/or also on the ocean.

Like this example.

One option I often use on my overland maps is to change the internal glow of the SHEET land to a lighter color (I usually use #29).

This color can simulate a "beach coast" in a simple and quick way.

Another way to further emphasize the coastal aspect is by mixing in other types of vegetation closer to the coast, as in the example.
