I know that, and I mostly use PonyDiffv6 with only specific negatives, but sometimes I needed the long negative prompt when it misbehaved.

@Fireside
You want your negative prompt to be short. From the PonyDiffv6 readme:

I found it just messes with the result if it is too long

@Background Pony #1FB5
Well, your version is a mostly different image with different atmosphere. I wanted to better out the original, so I had to use the same negative prompt, the same seed, step amount, and even the same sampler, because euler_a gave a completely different image. Still, your version is really good, too. Also, thanks for source_3d and source_comic negative prompt elements, I’ll use them as well (though my negative prompt is already pretty long by itself).

My Version
Still way to many steps.

Negative Prompt:
(score_4,score_3,score_2:1.1), watermark, ugly, bad anatomy ,bad hand , bad feet, source_3d, source_comic, (long body:1.1)
