Illustrious: i decided to do away with the varied fingers, since it seemed to confuse the generation. so now its always the middle 2, but it comes out a lot more consistent.

for pony:

i experimented using different tags for the number of fingers, with varying results

"First2"- your first 2 fingers. works well enough.

"mid2"- the middle two fingers, doesn't work that great, i set the CFG scale to 8-9 to get the best results.
"Middle finger"- works fine, but it makes everyone flip you off. should've used a different tag lol.
