Rejected PNG Image

I recently submitted a PNG images to Adobe Stock, but unfortunately, it was rejected due to quality issues. The message mentioned common issues like exposure, soft focus, excessive filtering, or noise, but didn’t specify what exactly went wrong with my submission.

I'd really appreciate it if you could take a look at the image (attached below) and share your honest feedback. I’m hoping to understand what could be improved so I can learn and resubmit it with better quality next time.

Any suggestions, tips, or critiques would be very helpful!

Thank you in advance for your support and time.
