Help-my composition sucks!

I will suggest to get closer to the foreground stone and take another angle from its flat surface (about 20 degrees more) in order to emphasize stone structure; switch to portrait mode orientation; very slightly change the perspective to high-to-low (or even low-to-high!); close the aperture to f/2.8-4.0 for the background to be eliminated; try to imply a diagonal line with objects in the background.
