Tree like :)

You really like islands - but they are pretty maps :)

Check that your machine is compatible with Win 11.

I updated to Win 10 on my laptop, and was then informed that it wasn't compatible. 18 months later it died a long, slow and horrible death. I only just had time to get a new PC in the end. 4 days later the laptop wouldn't even boot up.

Are there any plans of the internal layout online?

I think that is probably because they tend to get buried by the sand and chopped off at surface level by the waves relatively quickly.

This generally only happens to the largest ships, so symbols of those would be better done at city scale than dungeon scale, or the symbols would be awkwardly huge.

We need to have fish, of course! Huge swirling rainbow shoals of them.

Elementals too, I should think - symbols for Earth, Fire, Air and Water?

I have some nice Celtic knots I did for the wax seals that might look good, and then there is always Igdrasil.

Good - but I think the trees could do with some shadows?

Maybe not the best place to have the hole in the ground arrangements - right next to the well like that, but a good map :)
