I am not sure why my product was rejected due to quality issues.

Hello, I was rejected for quality reasons. My product is a model photo with a camera on the background, everything is of high quality. I know that the evaluation team may not have checked carefully, because I often have this situation.

You can't seriously claim that your pictures you posted here are of high quality. It is indeed your processing that introduced grave quality issues, and submitting again without addressing those quality issues will lead to your ban from Adobe stock. 

Even if these assets would get accepted at the second submission, as soon as buyers complain, the assets will be removed. If that happens often your account will get investigated. BTW: if they get accepted, the moderators did not do their job.

The face is blurry in each of these and the shadow is odd and unrealistic. The Moderators did the right thing in rejecting these. Resubmitting rejected images without having corrected the errors is considered spamming and can result in an account suspension.

This shadow needs to be removed. Re-uploading rejected without fixing any issues doesn't always mean the first moderator was wrong; it can also mean the second moderator wasn't doing their job.

The color of some parts is strange.

If you set keywords in advance using Bridge, you won't have to set them multiple times when posting.
