First of all, tones and colors are great!
Exposure, detail and sky are gorgeous.
But ( isn`t there allways a but?) some things could use some improvement
Most of all I`m having some trouble with your vertical composition.
The foregrond is too dominant and somewhat boring. By that I mean the pool has not enough interest to counter the dark and heavy visual mass of the boulders in the middle of the frame but at the same time it`s too big to be ignored.
Also, with this vertical framing you cut some elements in half. This gives me a somewhat cramped feeling while, to me, this image screams for a wide and horizontal POV. The boulders in the middle of the frame tend to create a second and more dominant horizon which IMHO disturbes the balance of the image.
I`m a little puzzled why you choose for portraitstyle framing? To me there are no strong vertical elements or lines that would benefit from this composition. Your emphasis seems to be on the foreground but I find the middle and the background much more interesting. Offcourse, this is the way of how little old me see things here, no disrespect or rudeness intended.
On a sidenote: there is a speck in the middle of the pool that attracks unwanted attention and the image looks a bit oversharpened. (but all that`s easily corrected in post).
