@nop related to hands i just have "extra hand, extra hands" and i think it helped a bit, but related to fingers i don't have anything, i just accept whatever it comes.
Some people that release models do recommend stuff like the "easynegative" lora/textual but i've used it and i don't like it's influence.
I don't know if someone has done it, but maybe the way of doing a good negative would be to make a LORA trained on BAD images and then use it as a negative, perhaps.
@ryuichi "easynegative" is good for getting different angles, but it has a significant impact on the output. Among those that improve finger drawing, I think badhandv4 is the best, but it still has a big impact on the output. Bad-prompt-v2 looks unnatural because the finger and body poses don't match. Although it has improved with model development, it's still difficult to cleanly show fingers with txt2txt.
