If it were mine, I think I would crop it much more panoramically, just below the yellow, so that you would have the dark silhouettes of hills leading to the deep red and orange glow of the sky. The bright yellow is so intense and there is so much of it that it distracts me from the mood set by the subtle differences of the various ranges of hills. The dark overhanging clouds at the top of the frame start a new idea altogether, so I would definitely leave them out.
Great shot.
