Adobe rejection of AI generative illustration for "Quality problems"

Hello, dear contributors, I follow this community and first of all I thank you for the time you dedicate and for the precious advice 🙂
I have sometimes received the following rejection for "quality problems" when I upload AI generative illustrations, like this one that I attach, and I would like to know how to improve the quality of the Ai generative illustrations and photos to be able to publish them on Adobe Stock. I currently use Photoshop and in particular the "Neural" filter for "zoom" and for the removal of "artifacts". Maybe it's not enough? As far as you know, are there any valid tutorials or courses to be able to create AI generative illustrations and photos specifically to be able to publish them on Microstock agencies? Thanks for your attention
🙂
