Using Lightroom I made minor adjustments in the Basic Panel except for Shadows (+100) and the Blacks (+77). This was followed by slight adjustments to the HSL Luminance colors (red +25 & orange +67). Adjustments in Detail and Tone Curve were minor.
I did find myself making local adjustments to the rock face, sky, icicles and leaves. My final edit was to remove the tree from the right edge of the original photo.
I would appreciate any input as to what I might have done differently.
