This is beautiful image as I see it and I don't think you could really improve on it. Same with some other postings. I can only relate my experience. Images shot with a 7DII on a tripod, mirror lockup and cable release with single shot AF. I tried several different lenses, including a 24-70 f/2.8 and 70-200 f/2.8. They did not compare to the critical sharpness I got with my 5DIII. That is when I decided to purchase a second 5DIII as a back-up and return the 7DII. If you are happy with your 7II copy, by all means keep it and enjoy. Don't be unnecessarily influenced by other people's experiences.
