The clouds and the mountains give similar bulk and shape top and bottom. The repetition makes the shot special. The central small area highlighted by sun is just enough to break up the foreground while creating a line into the image.
I find the frame too heavy. A much lighter grey perhaps?
Close up details with plenty of dof always appeals to me. I like to see natural details like this within their setting. The sun cooperated by picking out the thistles while the background is in shadow.
