Thanks in advance.
I'm sorry but I do not understand what you want to know.
Are you saying you submitted these photos to Adobe Stock and the reviewer rejected them for technical reasons?
Examine your images at 100-200% magnfication. The leaf is very noisy, details are lost. What kind of camera are you using?
When you say downloaded, do you actually mean uploaded?
Picture is out of focus, noisy and the lightning is not correct:
Post-production or in camera processing did add artefacts.
Idem for the second image:
I doubt that your Samsung phone allows for such extreme processing, besides the fact that anyhow the picture needs to be in focus.
And for your information: By refusing your pictures, Adobe stock gave you a reason, in this case probably Technical problems. Please give us always that reason with the picture. That helps.
And a second point: downloading is from the remote site to your computer. Uploading is from your computer to the remote site. This is sometimes confusing for non-native speakers.
