Knid, your work is excellent -- some of it is downright
amazing. I love the first tall tower, the Gates of Strength and Song, and the Garden -- wow.
I'm also floored that you're giving these pieces away. From what I've seen thus far, your work is easily good enough to be in print.
That said, here's an idea for you, if you are still taking requests:
Asmon Citadel consists of three separate areas: the Rack, a stocky, functional fortified keep; Virkune Keep, a lofty castle with and outer curtain wall; and the Citadel, a complex of caves and outcroppings cut from the living rock.
Seen from the side, and progressing from left to right, the Rack sits at the base of a large hill, with a bare arc of roadway leading from its interior up the hill to the entrance of Virkune Keep (totally exposed along its entire length). Virkune sits atop the hill, and a covered bridgeway leads from a tall interior tower to the side of a near-sheer mountain. The Citadel is carved into the caves that the bridge opens into, and from the outside appears as arrow-loops, protruding natural battlements, etc. The bulk of the Citadel sits about halfway up the peak (several hundred feet up), which remains near-sheer all the way to the top.
In terms of appearance, the Rack is all function -- thick walls, low towers, very defensive. Virkune is more "fantastic," although still solidly defensive. The Citadel looks like an evil beehive from the outside, full of scabrous holes (but also easy to miss from the outside). All three were built by different groups, and expanded and connected fairly recently.
I hope that makes sense. It all fits together in my head, of course.

Thank you in advance, should you have time to work this one up.
