Refer to the Stock Contributor User Guide. There's good information there.

Certainly if you posted these floral images to Adobe Stock, they would have been rejected for technical issues. They are all quite blurry and poorly composed. Don't bother uploading pictures of flowers to Adobe Stock; there are already many millions in the database, and yours will never get viewed or sold.
