Welcome to NPN! Glad to have you here and thank you for jumping in with your first post.
Thanks for letting us know you hadn’t really done much in processing - and it makes sense somewhat as this looks more like a RAW file - kinda flat and probably original white balance.
I think Matt’s comment/suggestions are right - and so I took it a step further and made some adjustments in PS. Please understand that these are just personal interpretations and may not fit your vision. But since we don’t know wha the vision is, I thought I would offer some suggestions.
First, took this in to Adobe Camera Raw, ACR (most use LR these days…) and I cooled the white balance a little and played with the blue saturation and luminosity.
Then in PS, I masked the sky, further deeping the blues with both Sat and Levels adjusment layers. Then I inverted the selection in to another layer and boosted the landscape a little more also with saturation and Levels adjustments (reduced the reds in the snow)
I’m not really convinced the snow would be so white given the time of day, but just trying to increase clarity.
Lastly, cropped a little off the bottom. Your original I think it was clear you wanted to give equal footing to the starry sky and the snow-dusted mountains, but it did leave the viewer with a bit of a 50-50 comp, which forces the question, what drew your attention? the sky or the mountain/snow.
This is just a quick pass, and of course editing a 1,000px jpg doesn’t come close to what can be done on the original Raw, but just for ideas.
Thanks for posting! We look forward to more and for your participation.
ps. - I think I went to far with blue sat. I was going for a “deeper” blue/black - deep space kinda presentation.
