The are generative AI and not photos. If you look at them at 100%, you see multiple compression artefacts at higher contrast regions. I also expect the images to be sharper.
Also the file type is incorrect. PNG should have transparency.
Above all you must NOT submit them as photos. Because they are not photos. If you did, that is an instant rejection, and you may be blocked.
Discard them. These are very dark and focus is not sharp.
Did you generate these AI as high-resolution diffusions?
Did you read the Generative AI Submission Requirements?
