[Flavio Miani]

Hello, i have sent a bunch of AI image of different animals with sunglass but they are rejected all for quality reason.
Can explain in details, thanks

Just looking at the parrot this is what  see.

1. The right side of the head is too pushed in.

2. The light reflection in the left sunglass lens is not good.

3. The light reflection in the right eye is from no light source.

4. What is the blue line in the left sunglass frame?

Parrot: the eyes do not match. There is lens distortion, typical to corrective glasses. Sunglasses normally do not have that.

Peacock: artefacts in the feathers:

Bear: artefacts in the fur: 

It looks like your AI generator creates the sharpness impression with artefacts and that upscaling does not address those artefacts, but in the contrary does engance them.

As Abambo mention artefacts all over. An in the one with the bear bad cut out, and it looks like the snout is pressed in.
