Having reduced the shock value a good bit I decided that they now needed a heavy weathering, I mean, who cleans up in the desert? They were in need of dust and dirt! I mixed a bit of Pewter Gray with Ochre and a goodly portion of white to get a dust color that looked like it went with the color scheme of the hills. This was heavily applied using a large stiff brush to the edges and flat surfaces of the hills to highlight the shapes while toning the colors down even further. You will find the results below.
Looking at it in the pictures I may have gotten a little heavy-handed with the drybrushing, but they will look better on a tan or sand colored table. I will have to come up with some sort of basing for the rock spires as they are rather tippy. At the bare minimum my Grots finally have someplace to hide from the Ork shootiness.
