What's wrong with my AI images and why were they rejected?

Knobs, knobs, knobs: check the knobs!

(Do you also see the rendering errors with the jeans?)

And then hands, hands, hands, check the hands:

The young lady in the hospital bed has two different hand styles: the one here in the picture is the hand of an older person, or at least fater person. Creepy.

The fingers of the patient in your middle picture are weird. The jeans, I mentioned. And then: 1) is the arm of a man, also quite creepy. It seems that your AI is doing a bit of Frankenstein's work.

Given all above, the doctor's doctor's coat arm is a minor issue. The "thing" under his hand is in line with the other Fankenstein issues.
