Ok, I came in late, so to try something different I cropped to a square format. Why should landscapes be landscape?
Edited in LR4. Cropped to 'thirds on the key peak (left top). Adjusted overall exposure and contrast, used a grad filter to darken the sky and then added some saturation there, used clarity and temperature to make the background distant range 'pop' a little more, added vibrance and clarity but de-saturated the closer mountain range.
Done quickly so some of the 'brushing' is a little rough (just like home - my wife doesn't let me apply the top coat...)
Great idea and responses everyone.
