Not sure why image was rejected

AI is notorious for poorly drawn details -- backgrounds, hair, hands, mouths, eyes, noses, ears, geometry....

• Closely inspect every quadrant of every Generative AI image at 100-300% magnification. 
• Fix the defects if you can, discard what you can't correct. 
• Compare your best work with what's available in Stock inventory.  If it's as good or better than what Stock has, submit it.  If not, cut it up for use in other projects.

That should cut down on your rejection rate.

For the abstract image, I noticed some random lines and specks when viewed at 100% and 200% that could be removed.

For the gorilla (and this is just me personally...my suggestion may or may not get this image accepted), I would remove the less than perfect lines that make the gorilla look part robot, part actual gorilla. The etchings in the forehead aren't as perfect as they should be and don't match from once side to the next, and I think it would be better if the gorilla were an actual gorilla, not half and half. But here's the rub: I would only work on once side of the face until all unnecessary lines and artificacts are removed (gen fill, the remove and content aware tools should be able to accomplish this with little effort). I'd then copy, paste, and horizontally flip the corrected side and use it to cover up the other side, giving you a perfectly symetcial gorilla in a robotic suit. I've done this with a good half dozen images, at least one rejected initially, then accepted on re-submission. Case in point:

Thank you.  I'm going to need to revist my process to better detect these issues.  

Zoom in and inspect more carefully. There are many incomplete and poorly drawn details on the gorilla's armor.
