I'm developing an RPG adventure map called "Tower of the Moon". It is designed by David Pulver, a well known RPG writer, and he provided some rough sketches. I translated those into an isometric map for the adventure. Here is the WIP. Still some details to add, then I'll color it.

If your curious, here are the rough sketches he sent (on the left), and my initial attempts to translate them into isometric.
