Constructive critique welcome, especially concerning the editing. The sun was gone for some minutes, but there were clouds that reflected some light into the valley. I kept it a little darker which looks really nice on the calibrated monitor (especially with a darker background color) but a little off on my laptop.
I took another one just of the moon and the rock. Unconventional but the more I look at it the more I like it:
Beautiful landscape. Nice color perspective: warm foreground colors pair well with cold middle- & background colors. Subtle blue sky tones and clouds look great. In BW shot these are lost. I would give it a try in colors too.
