Can someone explain why this ai generated image was rejected by adobe stock?

i had submited this ai generated image in adobe stock. but it got rejected. Can someone explain what needs to be corrected in this image? "Thanks for giving us the chance to consider your image. Unfortunately, this image doesn't meet our quality standards so we can’t accept it into our collection.

Common issues that can impact the technical quality of images include exposure issues, soft focus, excessive filtering or artifacts/noise." This was their comment.
