Rejected photos for out of focus and richness of artifacts???

Quality issues are anything, but were very commonly out of focus, exposure, and other issues for real photographs. As you submitted generative AI, exposure and focus are rarely an issue, but rendering errors are.

Keyboards are quite difficult to render correctly:

Generative AI has no clue what a keyboard is, so they draw something similar, but completely weird.

Lights are another issue, as they sometimes simply float around:

Other floating elements:

Then, your asset would have also got an IP violation, for rendering a crooked iPad:

You should avoid anything that remotely looks like an Apple device. And yes, there are also issues with the hands, like a missing finger, and a merging of finger and tablet:

But also the nose looks weird, as you should see partially more of the other half:

So the lady only has one nostril.

Then, you see really well the compression artefacts, either introduced by your JPEG compression, or even at an earlier stage with the rendering of the asset:

For the rest, I was really surprised not to see many clothing defects:

I'm quite certain that the Moderator looks first at the hands in AI images. It would have taken just a few seconds for the Moderator to find the errors in the hands and press the reject button. You should be inspecting your images by zooming in to 100-200%.

Not about focus or artifacts. Rendering and logistic errors.
