This reason means that your content doesn’t comply with our Contributor Agreement. Content may be non-compliant due to watermarks, inappropriate or irrelevant keywords or image titles, or questionable, or defamatory content. Your file is also rejected as non-compliant if you receive a reminder to submit a model or property release, or resolve a problem with a release, and you resubmit the file without addressing the issue.
I should say it needs a property release, but the first time, Adobe would say so. We can't see your keywords or titles, maybe it is that?
