UPDATE:

USE the recommended Lora art-full or any other cinematic Lora to counter-balance this one. It makes results significantly better. My Lora should be set at -1 and the art-full Lora at +1.

Use at -1 for better images. It literally obeys your prompt words better (to an extent).

You'll see in the example images that base PonyXL doesn't have equal prompt understanding to this Lora set on negative.

Use at 1 or more for extreme ugliness.

There was no negative prompt in all the example images.
