This is a fascinating image. It was special right from the start or I would not have taken it. But why? Everything is ‘figure-out-able’, so here we go.
After looking at it for some time, I realized what the special quality is and I have edited it accordingly: strengthening this unusual ingredient.
The distant mountain and the two close rocks have similar slopes on the right edge. These slopes create implied diagonal lines. The image looks best if these three implied lines are nicely aligned and balanced.
To make this happen the image needed slight stretching and slight cropping on the left and bottom.
