Surprisingly at very low strength ie: 0.1, this seems to actually make hands and fingers come out much better.

So far it seems to run best at around 0.2-0.3 strength. at 0.5-0.65 it also seems to create good pictures though these tend to be more intense.

Disclaimer: As it is now the lora tends to go overboard on adding injuries to characters at a higher level. It also seems to default to making characters female or more feminine. This can be remedied by adding "male_focus" to the prompt for male characters, "bara" also seems to help if male focus isn't doing it. Further prompts like "Masculine" and "manly" seem to help reduce this further but then you end up with hyper masculine muscle men.
