Nature

Probably rejected for technical reasons. 

The visual quality is very pixelated.  Probably because it was taken on a low-res setting with a less than stellar camera.  Although nice to share with family & friends on social media, not good enough for use in a million dollar commercial print or digital ad campaign which is what Adobe Stock customers expect. 

Best of luck with your next submission.

Please give the exact refusal reason. This is important so that we do not need to guess.

Picture critique: Out of focus, bad contrast.
