Good morning, I would like to know the reason for rejection of this image? For feedback
You didn't indicate the rejection reason. If you did not include model releases for the young ladies, you would have received a rejection in that basis. It's also underexposed with a blue color cast, so would have been rejected for technical issues.
In addition, the picture is noisy (colour and luminance noise).
Much too much blue. Adobe Stock expects photos with a neutral white balance.
And did you submit signed model releases to use both girls commercially? If they are under age, their parents must agree and sign the forms.
