Why were my ai generated images rejected for alleged quality issues? Which quality issues did they have?

I recently submitted three AI-generated images to Adobe Stock and would appreciate honest critique from experienced contributors, especially regarding technical quality and whether these issues are typical AI-generation problems.
The rejection explanations feel somewhat broad/vague to me, so I’m hoping for more specific insight into what reviewers may have seen immediately.
Rejected images:

I understand Adobe Stock reviews AI submissions very carefully, especially for:
- artifacts
- overprocessing
- unrealistic textures
- anatomy issues
- noise
- oversharpening
- generic/repetitive concepts
What I’m trying to understand is:
- What specific problems stand out immediately to experienced reviewers?
- Do these look like typical “AI-generated” failures?
- Is the upscale itself potentially causing the rejection?
- Are the concepts too generic/saturated for Adobe Stock right now?
- Does the “Similar Content” rejection likely mean similarity to my own submissions, or similarity to the broader Adobe Stock collection overall?
I would genuinely appreciate blunt, detailed feedback. I’m trying to improve both technically and creatively before continuing to upload larger batches.
Thank you.
