Its everywhere.

The first thing I noticed was the weird ball in the middle, its close to correct, but wrong in a way that doesn't convey or add anything. Like its not "melting" or "covered in blood" or subtly hiding a face or anything. Its just "wrong" for no apparent reason which is weird since it is a centerpiece.

Next is the wildly inconsistent level of detail, often with sharp transition. Look closely in just a few spots and you will quickly see the detail go from near realism to extremely blurry, again, for no apparent reason.

Its just stuff like that that, if done by a human, would have more meaning or at least consistency.

Blender has recently had an AI pic-to-pic like feature added (modded? idk I'm not an artist and I don't know blender or PS) so maybe that's what Andres meant, but I doubt it.
