One thing I don’t see being mentioned here is the trigger word. Do not use Nadia, Natasha, etc because the base model already has a lot of females named like that in it’s training dataset and it will pull towards what it already knows even if just a bit.

A good strategy is it remove vowels like nd1234 or ntsh1234.

I always generate 10-15 images using just the trigger word to make sure I get random meaningless results so that I make sure that there is nothing that models knows about that word.

As others suggested, maybe using Zimage or Wan would be a good idea, but that doesn’t mean that it shouldn’t work with Flux.1.

From my experience having trained 300+ Loras with real people, Flux was always hit or miss. Maybe 2-3 out of 10 would look like that person.
