Hi Judith,
Yes, that's a good call on the compositional aspect and generally*, its implementation.
* There's a minor issue with a 'sawtooth edge' down in the brush on the left.
I guess like the observer of someone painting a wall, I should "Oi, you missed a bit"
I think you are right. I will correct it this evening. It is a bit lost in the brush.
With regard to the tones adjustments, I now see, especially over on the top half of right hand side, in front of the large rock, a darkened halo just inside the edge of the image, which looks odd to me.
I am not seeing it yet but will look again this evening. I appreciate your close inspection! Really!
HTH, Dave
PS
Good pics from your cell phone!
