Hi Peter, It certainly has potential.
All thats missing from your shot is a dramatic sky, IMO.
Here's my attempt at bringing the sky detail into the shot.
I've adjusted the levels, so that the black/white sliders touch the bottom of the histogram mountain.
Using the magic wand tool, I've selected the sky area, created a new adjustment layer for levels, moving the black slider in to bring back the sky.
I've also added a saturation layer, and adjusted the brightness and contrast slightly.
