PNGs, Photos rejected , quality issues

[Md. Amir Hossain1981]

I have submitted some PNGs, Photos ware created by AI but was rejected due to quality issues. I would like to ask for advice on what might have caused the rejection. 

Thanks in advance.

Focus and overexposed highlights is an issue in the first image. (By the way, not photo).
AI learns by examining photos and images. This means that AI is capable of reproducing errors in photos when creating images.

The strawberries are either too shallow or out of focus.
Some of the water droplets on the outside are transparent, and some are not.
Also, they would look more delicious if they were a little brighter.

The background of the mango is slightly transparent.
I also like how the original background color still remains faintly on the outer edge.

Too cartoonish 3D, not photorealistic 3D!

The juicy mango has multiple issues: 

The droplets on the border need to be transparent, they are water droplets!

The AI generated some artefacts. 

In addition: the mango is slightly transparent, something like 1 or 2 %.

The balloons have artefacts and rendering errors, everywhere:

Random, imperfect rendering errors with the paper party favors.
