Image rejected due to "Intellectual Property Refusal"- Looking for feedback

Hi everyone,

I recently submitted a photo I took, thinking it might be something others would like enough to use themselves.

I would appreciate it if you could help me understand what exactly might be wrong with the image and what I can improve for future submissions.

This is the rejection message I received:
> "During our review, we found that it contains elements that appear to be protected by intellectual property (IP) laws, so we can't accept it into our collection."

I've attached the image below for your reference.

Any constructive critique or suggestions would be greatly appreciated!

Thank you so much for your attention and participation.

Best regards,

Paul Riley
