I made this map some time ago, maybe it will help as a reference.

@Royal Scribe I found it in the Trash bin of my computer. This was the image used in Moon Islands.

I'm trying out a new possibility:

1. Create AI-generated images of maps that come with interesting decorations.

2. Use this image as a Trace and add Transparency to this Sheet.

3. Place the Sheet Trace under the Land, and draw the outline of the Land on top of the image.

4. Arrange the map as I see fit with the chosen motif and keep this sheet trace transparent when I export the JPG.

I'm attaching the image and the file; I think you'll just have to "fit" the image back into the trace to get a better idea of ​​what I'm talking about.

Cheers
