The model I think is fairly self explanatory.

Works well at a variety of strengths from .3-1. Higher strengths might have a bizarre thing where the hands and fingers get wrapped in cloth, but that issue seems to resolve when you get down to .6-.7, when mixing with other LoRA it doesn't seem to matter too much if you have to drop this LoRA down to a strength of .2-.4 to not override the style/character you're using, it seems to largely just work. Works for basically any position a person would be in to be behind a person to pull their arms back, standing, kneeling, pov, facing you pulled in the opposite direction. I dunno, just werks.
