why my image rejected

It should have an IP rejection because the name Junkai is readable on the front tire.

You should upload a full-sized image.

And also, this image probably won't be accepted due to Intellectual Property - IP restrictions.

Have a read about IP release requirements:

Please provide the full-sized image as initially submitted. We can't tell much from the thumbnail alone. ]
