Thanks for reaching out.
Would you mind sharing more details on what are you trying to do? What is the version of the application?
Can you tell us, how is this image rejected? Do you get any error messages?
We're here to help. Just need some more info.
I think this belongs in the Adobe Stock Contributors forum. But it is absolutely unsuitable for stock, for several reasons. Especially the signature.
Moving this to the stock contributor forum.
What was the rejection reason?
If you are new to stock, you should consider these resources: https://helpx.adobe.com/stock/contributor/tutorials.html
Please read the contributor user manual for more information on Adobe stock contributions: https://helpx.adobe.com/stock/contributor/user-guide.html
See here for rejection reasons: https://helpx.adobe.com/stock/contributor/help/reasons-for-content-rejection.html
and especially quality and technical issues: https://helpx.adobe.com/stock/contributor/help/quality-and-technical-issues.html
Before you spend any more time preparing images for upload to Adobe Stock, you should read ALL of the material on the Help pages, particularly this section which clearly states the dos and don'ts of stock photos. The white frame, the signature, the filters and the unnatural processing will all earn an immediate rejection.
I agree with all remarks so far. I will only add that abstracts & flowers are a low percentage sellers. Stock inventory already has 26 million perfect flowers of every possible size, shape, color and variety. The competition in this category is very steep.
Be creative in selecting subjects. There are lots of interesting things to submit besides plants, flowers, sunsets, clouds & pets.
Better luck next time.
