Newbie asking for your guiance on the quality of my photos

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

Your pictures are oversaturated, contain optical defect, like chromatic aberration, artefacts, exposure issues, white balance issues, and composition errors. Check your pictures at 100%. You will see many errors, as they are really easy to detect. Photos require to have an as close to natural look as possible. I suppose you are using a phone camera and you are using some automatic filters for processing. That does not work.

Compare your best photos with Stock's inventory to assess if yours can compete with what Stock currently has.  They already have millions & millions of sunsets, so the sales potential for another one is very low. The trick is to find a need and fill it.

Customers are always looking for commercial quality images that depict diversity, lifestyle, tech, travel, business, education & leisure.

Hope that helps.

The first two images are much too blurry and lacking in detail and also appear to have been overprocessed.
