png cutout got rejected

Check this out: 

Red: background removal issues. And I even did not check all of the issues.

Green: if you have multiple objects, they should not touch each other. It will be impossible to separate those, so they will be useless. A potential buyer will probably want to select some of the objects, to include them in their composition. That won't be possible here.

can anyone explain why this image got rejected   ? i used adobe express for the removal of background!!

this is my first time uploading png cutout, and why software we can use to avoid rejection!!

Adobe Express, as all automatic background removal tools is not perfect. Background removal is best done manually, the hard way, by carefully removing the background using a tool like Photoshop.

I use Photoshop. After the initial automatic selection, it is necessary to zoom in and carefully refine the edges to ensure a perfect cutout. Then view it on black as @daniellei4510  has demonstrated to check the results.

Using any background removal program is usually fine for personal projects, but for commercial work, there are none out there that will remove the background perfect. It must be done by hand to accomplish perfect cutouts.
