quality standard rejection

Hi. I have problem with subbmision, but th funniest things is that I sold same files on shutterstock and adobie stock few times… Those are few 3d render in hudge reslution ~11000x4200px . Is there anyone who can explaine me why they reject that files? :slight_smile:

I will be very glad and happy if someone told me more than “not enought quality” as they write to me.

Kind regards for everyone Daniel
