Why Were My Images Rejected? Need Feedback!

Hey everyone,
I recently submitted some images to Adobe Stock, but they got rejected, and I’m trying to understand why. I’d really appreciate any insights from those with more experience!

Here are some of the images that were rejected.

Some of them are illustrations of furnitures but there's so many abstract portraits. idk why i got rejected.
I checked the guidelines, but I’m not sure if the issue is with technical quality, composition, or something else. Have any of you faced similar rejections? Any advice on how I can improve for future submissions?

Thanks in advance! Looking forward to learning from your experiences. 😊
