The photo is already beautiful as it is. But I think that with a different crop and some levels and curves adjustments, the overall composition becomes better.
I first set the white and black points with levels. (hold the alt and move the shadow and highlight slider inward untill you see black and white) I then created a curve for some more contrast in the sky. I masked the FG, lake and shoreline. Both actions done with adjustment layers.
I then cropped part of th sky, so that the horizon moved toward the 1/3 line and so that the mountain looks higher. IMHO, the sky wasn't adding anything to the composition.
I hope you like this different POV.
