I'd say tweak the snow some, make it more varied to give it some depth. Bigger bits, smaller ones, and blurry ones that are right up against the camera. The mountains themselves are excellent, though they seem a bit blurry if I zoom in on them. Is this a screenshot, or is that just for the 1:1 scale effect?
Also also, that text in the text box isn't centered and it looks weird, as someone who's used to left-aligned or centered text.
