help me to understand better the QUALITY ISSUE in my image

Hello everyone,

I'm new here and tried to upload AI generated images. They said i have 'Quality Issue'.

I already read https://helpx.adobe.com/stock/contributor/help/quality-and-technical-issues.html,
and from that source, maybe my images have overall quality lacking. but, as a newcomer, to be honest, i don't know what to improve from my images because my lacking understanding and experience.

please help me to understand and point the problem specifically and detail so i can be better. Thank you 🙂
