Adobe rejected these two pictures and saying that- during our review, we found that these images are not completely sharp and in focus when viewed at 100%, so we can't accept them into our collection."
Can anyone help me to figure out what is technically wrong with these images?
It sounds pretty self-explanatory. For what it's worth, the images look blurry to me too. It's a combination of motion blur and a shallow depth of field. Next time, try shooting at a higher shutter speed. I mean, I know the wings will be blurry, but too much other stuff is in these images.
