Yes, thank you! I've seen the first one before but it's handy to have the tutorials all in one thread. Much appreciated!

I decided against trying to "erode" the levels of the ziggurat. It was a lot to change, and I decided that I will keep the technique in mind next time I do one. Instead, I focused on adding layers of the sand texture to each level of the temple (except for the top portion that the priests are more diligent about sweeping). I tried to vary the patterning by starting drawing from different corners, but I'm not sure that helped much. I might alternate which of the sand textures are used, as I did set each to different scalings. I like the color and scaling of #4 the best but I really should change it a little so you don't see angled paths of no sand like on the north face.

I also added the edge of a mountain using the same techniques as the dunes, but with the bevel isn't smoothed as much, and I used a dark brown earth fill. Maybe I should move the mountain to the NW or NE corner?

I decided I didn't want to redo the entire tower, so I did some stairs ascending around it from the courtyard as a proof of concept. I do like the idea of stairs winding around a tower. Wonder if I can make it go around multiple times? I have some thoughts on how to do that, but I will save them for another map.

In the meantime, here's how it turned out:

(It's subtle, but beneath the railing there are railing posts, which you can't really see but they cast a subtle shadow.)

Anyway, I'm rushing out the door, but I will make any tweaks when I return and then re-export the maps that show the tower.

If the ProFantasy Gods are listening: a future annual that I think could really complement the Marine Dungeons would be a "Jungle Adventures" dungeon. It would provide an opportunity to bring in palm trees and coconuts that could also enhance Marine Dungeons. Maybe some swamp building tools, including tree trunks with the ripples used in Marine Dungeons? Lots of colorful jungle foliage. Maybe some giant mosquitos or other bugs? Alligators or crocodiles? Think of the Indiana Jones-inspired adventures! Golden idols! Whips and fedora hats! Aztec-inspired ruins. Maybe a perfectly round boulder for traps. (The opening scene of Raiders of the Lost Ark is my favorite action/adventure opening scene of all time.) Just planting an idea....

And here's the lighthouse at night. Fires are kept burning all night, reflecting off of mirrors (or polished sheets of metal) to cast light away from the mainland, though a window allows for some light to spill into the courtyard.

By night, a glow from the sunken ruins reveals a magical portal beneath the waves....
