Hi @Abas24434653sumz , you would have been given a reason from Adobe with the rejection (Technical Issues, Intellectual Property (IP) Violation, Missing Model Release, etc.) In your photo I could see all three of these issues. It looks like your photo was taken with the camera on your phone. While you can get some great photos for social media posts, it is more difficult (but not impossible) to get stock quality photos. Looking at your image at 100% magnification there seems to be lots of compression artifacts, halos around the power lines and buliding structures and some colour artifacts by the bird in the upper left corner. The bird itself should probably be cloned out as well as it isn't close enough or clear enough to add value to your photo.
The logos on the people's clothing would cause IP violations. Those logos would need to be removed.
A model release would be required for any recognisable person in the image. The test is not whether we could recognise them, but whether they could recognise themselves.
Potentially, you may also need a property release for the location you were at as well. Some historic sites allow for commercial photography, whilst others have restrictions. Here is a link that provides some guidance. https://helpx.adobe.com/stock/contributor/help/property-release.html
If you are new to stock photography, here are some resources that you might find helpful:
Best of luck in your future submissions.
