photo was rejected for "technical issues"

Quite the same as your prior (second?) post (https://community.adobe.com/t5/stock-contributors/photo-reject-for-quot-technical-issues-quot/td-p/11949859😞

Counter-light pictures are very difficult to take. Your camera did not get the trees sharp, there is a lack of contrast and probably also an over exposure. There is also some chromatic aberration in the image, as I would expect for such an image even with a good prime lens.
