It feels like your primary subject, the rock tower, is too centrally located in the composition, which reduces the context too much. My first inclination is to suggest that the tower be further to the left in the image, perhaps allowing you to capture more of the trees in the foreground, which would make them feel more like a part of the image and give better foreground context. That might bring too much of the peak on the right into play, though, which could confuse things in its own way. Alternately, you could bias the tower to the right and get rid of said pine trees altogether, using more of the darker, plant covered ridge on the left as your primary context. Both options would be a little more dynamic and draw the eyes toward your subject in a more natural way. A final option would be to go for more of a portrait style for the tower, zooming in so that just clouds surround it, which would get rid of the context issues altogether and focus more on the textures and whispy clouds.
