Rejection of image due quality issues

Hi.

I am now very upset about Adobe. I see so many AI photos on Adobe when I search and the review takes way too long.

My photo was rejected due Quality issues. I now use Topaz AI to sharpen my photos. Unfortunately it doesn't work with that either. What do you think? Is the photo too dark and the sky not blue enough? Is the white of the flag too dark? Is it about the artifacts on the blue fabric? The fabric is shiny, so this won't work any better.

Thanks Chris
