The quality of light is amazing, like a rainbow light coming through. I find the crop too tight rendering the mountain too central; it cuts off the sweep and line of the mountain on the right side, where the slope practically begs for more exposure. I guess one could have gone to the left also, but the right is more suggestive in this crop.
I see very few landscapes that I do not think would be improved by cropping/using a longer lens... I did not immediately think so with this, but you could try a longer lens and a vertical format - I do like vertical landscapes.
