@JOY98A6 These have depth of field and focus problems. The prominent leaf is too far out of focus in the first image and the cropping/composition seems too severe. Be sure to examine images up to 200 percent in all areas.
If you zoom in to 100%, you'll easily be able to detect that very little of the blooms are in focus. In addition, as Jain indicated, you have cropped off too much. Keep in mind that the buyer can also crop in themselves if they wish. Shooting wider will give them that option. Images of flowers are in general highly over-represented in Adobe Stock. In order for yours to be accepted, or ever sold, it would have to be perfectly exposed, lit, composed and edited. Search on "purple+iris" in Adobe Stock and you will see nearly 75,000 gorgeous images!
