This already gets a big thumbs op from me simply because you dare to have 90% of the surfaces in the shade, something not many do/dare.
I also like it you chose a not so common aspect ratio for your image, but in order to make it really work I think the foreground needs some more interesting details.
The rocks are a nice addition, especially the one on the left I think integrates well in the scene. The one on the right not so much I'm afraid.
Perhaps a bit cheesy suggestion, but something like a path through grasses towards the lake will compositionally help the viewer to see the nice lighting on the mountain.
At the moment there's not really a "leading eye".
Else it just looks pretty solid to me, I like seeing your work every time!
