Rejected for quality issues

Hello, I recently submitted several photographs to Adobe Stock, but all of them were rejected for quality issues. Since the rejection message does not identify the specific problems, I would appreciate some detailed feedback.

Could you please check whether the main issues are focus, noise, compression artifacts, exposure, white balance, or something else? Some files may have been transferred through a messaging app, so I am also wondering whether compression caused visible quality loss.

I am approaching Adobe Stock as a casual side project, so I would particularly like to understand how to identify photos that are suitable for submission without extensive editing. Thank you for your help.
