I rather struggle with this - you really want the main subject, the mountain, to be well lit, instead of which you have a well lit sky and foreground. So I've attempted to reverse that - tho' would go back to my original shots and probably pick another, to be honest
Darken/Detail in sky, lighten mountain and darken the foreground line of trees. Used dodge and burn and increased yellow/red saturation to "light up" the mountain
