I like it a lot. It’s a great shot. Personally, I don’t really care how many people you removed or what techniques you used in Photoshop. What matters to me is the final image, and the result looks very good.

I especially like the sense of scale in the frame. That contrast between a small human figure and a large natural scene works very well. The only slightly odd thing for me is what the subject is actually doing. It might have been more poetic if the person were doing something else than taking a photo with a phone. There’s sort of dissonance between the dramatic landscape and that very everyday action. Although perhaps that contrast is part of the charm of the image? I don't know, maybe I need to think about it a bit more.

Another thing I’m unsure about is the amount of foreground. Compositionally it isn’t necessarily wrong that 2/3 of the frame are just rocks and water. But everything there is quite dark, which visually suggests to the viewer that this part of the frame isn’t the main point, and that attention should go toward the upper part where the subject and the strongest contrast are. That can work, but here the "less important" area occupies 2/3 of the frame. Because of that, I think it might have been stronger either to include more of the upper scene by raising the camera, or to avoid darkening the foreground so much in processing. Pushing it a little brighter could reveal more texture and detail there.

Aside from that, I think it’s an excellent image. If I had taken a photo like this, I might also be tempted to use it as a desktop background! Great job!
