I just want to say first off that I personally am a huge fan of these sorts of shots.
However, I think it could be improved with some editing of the colours to create a vaster array of tones in the piece. It looks like it has some blue undertones which would have come out very well if edited further.
Also, I think some editing in regards to the contrast or even a smaller darkening of the photograph might have helped to create a deeper silhouette of the mountain. Right now, it's very flat and comes out quite grey. The colours in the piece would be more effective if some of the grey colouring was darkened, which would create a greater impact for the warm tones.
Hope this is helpful.
It is a wonderful shot.
