Made for a friend online just to show them how easy training a lora is. figured i'd upload since it works alright. (i will not be improving this further as i have no interest in it)
It's not perfect, results are cherrypicked, combine "joi_gesture with one hand" with "one fist on crotch" to prompt this.

all it does is help with the little bit about how the fist itself is positioned.

it's just a rough proof of concept as i mentioned, and trained on realistic 512*512 images (but will still output fine at pdxl 1024*1024 ig), so this will affect your styles if you try it on a 2d model, even though it was trained on autismmix ponyxl. might be rectified by adding other strong 2d style loras, but it will affect it.
