Rejected - Technical issues

Who owns the lion?

Did you get the owner's written permission to use the animal's likeness commercially?

I agree with the reviewers.  The technical quality in these photos is not good enough for Stock.

Adobe Stock customers expect perfect images with balanced color, good exposure and sharp, crisp details suitable for professionally printed projects.  These images would not reproduce well on billboards, posters or T-shirts.  Sorry.

Noisy and blurred. The lion has washed out highlights. You may need a property release for the lion.

Needless to say, I agree with @Marianne-Deiters!

Adobe's vetting process is optimized for speed. The moderator refuses on the first error he sees, and the refusal reasons are standard texts, giving you only an indication of what is wrong. You need to know that this is not a photography course, and writing an extensive critique would by far cost too many resources. In addition, contributors and moderators are internationally located, and you simply could not return a text in each language.

Please check your images at 100% and 200% for focus and artefacts. Only correctly exposed images that are in focus and which do not expose other faults get accepted. If you are new to stock, you should consider these resources: https://helpx.adobe.com/stock/contributor/tutorials.html
