The example images show the before (left side) and after (right side) without and then with LoRA engaged.

As a quick filter, before an i2i, this image seems to draw out some characteristics of the secondary model that's used as a refiner and augment in ways that may otherwise have been passed over had it not been for this priming.

Aside from that, on a less mysterious topic, this will add back some of the synthetic appeal, though with careful adjustment a tweak of detail has often taken place.

I added some other functionality to this and got a little carried away so you'll be careful when putting a male figure in with a woman because she seems to enjoy using her hands.

In any rate, I like the synthetic look of the images when augmented by this LoRA just a touch, though at lower weights it can have a "cleaning" effect, reducing or eliminating the fuzzy artifacts. That has been my experience anyway.

I love the real "feel" of Z-Image and, at a heavy weight, this LoRA could obliterate that new experience but the right balance can give an image that delicate pop that seems to be missing, without over saturating it with a polymer esthetic.
