Sun has almost set

This would be the last update of this painting before finishing. I started working on highlighted areas and cutting into rock shapes. I need to be careful not to make too light for too much areas. I think I need to make three color values 1) light snow area, 2) dark shadowed snow area, and 3) rocks. And gradually reduce the value range among them while I work from top of the mountains toward the bottom. Then it would be done.
