The Adobe Moderator would have given you a reject reason which I assume was "technical issues":
1. Soft focus, halos along the edges from over-sharpening or other processing, chromatic aberration
2. Not in focus; blown out highlights, noise in the shadows
3. same as no. 2
4. Focus is not sharp enough; noise in the shadows
5. same as no. 4
Keep in mind that Adobe Stock is already saturated with flower images; in order for yours to be accepted, they would have to be perfectly executed in terms of focus, exposure, lighting and composition.
Hello @Rameswar Mishra , look at your photos at 200%, if you do, you can see artifacts along all of the edges of the first photo. Also, your shadow areas are slightly underexposed. The other photos I did not look at.
