can you help me why my work is not accepted and how to fix it?

Sorry to say, this is not a suitable image for Adobe Stock. 

Customers want perfect images for use in their commercial projects:  brochures, posters, product packaging, movies, TV, videos, advertising, merchandise, etc...

Better luck with your next image.  🙂

You posted in the wrong forum. I will move this from Stock to Stock Contributors.

What was the refusal reason? You should always post the reason Adobe gave you.

What I see is that it is full of artefacts, colour noise and other defects.

Customers expect “clean” and “usable” assets. This one would be returned on the spot.
