Interesting, I saw it as Rich described it: the terrain dips and then rises again further in the distance. So it worked for me on first viewing. But once I saw other people's comment about the scale issue I could see it.
Regardless a really wonderful image in my view. Combining those amazing rock formations you are coming up with and some great vegetation, sharp and smooth areas naturally flowing into each other. For me it is very evocative.
