Technical Error

Chapelphoto is correct - you have chromatic abberation around the petals. You have to also correct for this.

That yummy cake seem to be one of the subjects, however how I read your picture, you wanted to do a close-up that includes the flowers, and the crumbs from the cake. In trying to do so you cropped all the subjects. In addition the photo is also out of focus. These are the reason for the rejection. A better approach would be to have a wider composition to include the entire cake, flower and crumbs. This allows the buyer the option to crop in whatever way he wants. For example if he wants the cake only, he'd have the complete slice of cake. Here are some  Do's and don'ts for selecting and editing photos for Adobe Stock . It would be good for you to go through the relevant links at tagproducts_SG_STOCK-CONTRIBUTOR_i18nKeyHelppagetitle . Pay special attention to the "Adobe Stock Contributor Guide".

Good luck

Hi there, for your photo, I think composition is an issue. The blue squares cut the photo in half. I also think white balance could be a problem. It's too blue. You need to warm it up a bit. But I would also change your composition.
