Feedback Request: Rejected Image (Quality Issue) – AI-Generated (Firefly 4 + Upscale)

Hi everyone,
I recently submitted an image to Adobe Stock that was generated using Adobe Firefly (Image 4) and then upscaled using an AI upscaling tool. Unfortunately, it was rejected with the message:
"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."
I’m trying to understand exactly what quality issue might have caused the rejection — whether it’s something related to sharpness, detail, artifacts, or something else.
I'd really appreciate if some experienced contributors could take a look and give me constructive feedback. Here's the image:

Also, if anyone has tips on:
How to prepare AI-generated images for Adobe Stock
Recommended tools or settings for proper upscaling
What specific quality standards to look out for
...please share your insights! I'm hoping to improve my submissions and learn from this.
Thanks in advance,
