Many models can do face tattoos pretty well on their own. But for those that can't... they really can't. Even if you crank up the weight like (face tattoo:2.0), chances are that you will get tattoos everywhere except on faces. So, I create this LoRA to enhance face tattoos.
For example, here are some comparisons using Homoerotic v2 (which, while being a good model, sadly cannot do face tattoos very well), without/with this LoRA:
Disclaimer: Some models used in my sample images (such as Realistic Vision and Ally's Mix III) can do face tattoos on their own. You don't really need this LoRA with those models. Or, if unfortunaltely you have trouble with those models generating face tattoos, use this LoRA as an enhancer.
