This LoRA collection works better for INPAINT/EDIT, but it does a good job on txt2img too.
I was having a problem generating images with people who have piercings (nose or lips). Flux doesn't know how to handle that properly, and even training a LoRA for a person with piercings resulted in awful results.
I found some piercing LoRAs, but I noticed a common problem: Flux needs to be trained on the specific side of the face where the piercing should be, otherwise Flux will put the piercing on both sides.
So, I trained it focusing on the correct sides, trying to fix this. It's not perfect, but it works well!
Trained so far - SELECT THE TYPES AT THE PAGE TOP:
ring nose septum u-shape
lip piercing centered
medusa piercing centered
Because the training data used close-up shots (to avoid changing generated the faces), it might not work as well when using txt2img with faces that aren't in close-up. Then generate without it and then use the lora with Klein edit.
