Thanks for all this information. I'm realizing it really does require a lot of time, trial and error, and a great deal of patience and tolerance for failure.

For training a LoRa, I tried OneTrainer, and it wasn't as straightforward as I thought at first, but Claude.ai helped me configure my first LoRas, and it's actually quite simple.

For your project, you would need two LoRas, one for each woman, with clear identifiers. The names you gave them could be the triggers for the LoRas.
You would need to generate 50 different images of each of the two women and train their respective LoRas.

Intuitively, that's how I would have done it.
