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.

A friend of mine is passing the baton to the next generation. His 9-year-old son is playing with his school friends and he is the GM. They asked me for a map, so I tried to make it as simple as possible.

The locations are: Castle Measles, Dark Swamp, Ruins of Oblivion and Magic Tower.

The other spots are "names": makuka, taluka and blau.

For this map I used a wide variety of icons from the Annual Dark Fantasy.

Using Myrr Overland Annual and a small section of the Norwegian coast to compose a very minimalist map.
