Michael,
Nicely composed. I would agree that it feels a little flat, and I also wonder if the color temperature isn't a little too cold. (I appreciate that this may be closer to the way the scene really was when you were there.) Local Contrast Enhancement would likely help to bring the foreground closer and push back the background to give it some more depth. LCE is really an umbrella term for a number of different techniques that achieve the same thing, but Unsharp Mask at 20% and Radius 50 is a good starting point.
I like the composition - well done. The arc in the FG coincides nicely with the arc of the spires in the BG. You have good balance on the left and right side of the image with the larger middle ground rock faces. Agree with David on the cool tone and contrast.
