Please help explain the quality issues here.

Your assets have been refused for Quality Issues. But that you know. You need to post one image in the same quality as submitted so that we can help you to point out the quality issues. If afterwards you analyse your images the same, you will find most problems in your images.

If you are new to stock, you should consider these resources: https://helpx.adobe.com/stock/contributor/tutorials.html
Please read the contributor user manual for more information on Adobe stock contributions: https://helpx.adobe.com/stock/contributor/user-guide.html
See here for rejection reasons: https://helpx.adobe.com/stock/contributor/help/reasons-for-content-rejection.html
and especially quality and technical issues: https://helpx.adobe.com/stock/contributor/help/quality-and-technical-issues.html

The members of this community are not Adobe employees, and we have no ability to look into your account to view rejected assets. You'll have to post them here.

The file ID's mean nothing if the images were rejected. You need to post the actual images here.

I only see screenshots of the rejection notice, did you attach the actual images to view?
