Hi @RedCharly ,
The flower is out of focus, and poor composition for the building. The perspective is not correct. Also there seem to be color fringing around the shadow.

Don't clip your subject.
Good Stock Photography is realistic. Adobe Stock customers are rarely seeking abstract art.
It's important that your camera is pointing directly at your subject and subject should be well-lit and in focus.
Thank you for your suggestions.
I will spend some time on the suggeted articles
