This is a very nice image. I'm not that fond of the red/brownish surfacelayer but for the rest the colors look really fine.
Cool rockstructures and nice strata, especially on the overhangs. Good settings!
I also suggest to break them up using a powerfractal as blendshader on your stratashader.
First I'd check the powerfractals distribution on the terrain, you can do this by using the powerfractal either as a childlayer of a surfacelayer or as a surfacelayer itself. Increase contrast and play with scalesettings. When they look fine then just simply use that powerfractal as blendshader for your strata.
Maybe you already know all of this, but if you don't you won't have to wait for me to explain

The rock structures on the very bottom on the image have some texture/displacement (not sure) opposite to the strata. I think they look really cool!
