If you like it, consider buying me a coffee, I'm poor.

A few details:

It was trained on Stable Diffusion 1.5 as a base model, so it might work on most checkpoints without many alterations, my favorite checkpoint for this was Real Dream Legacy SD1.5. For incredible as it may sound, it works better in normal realistic checkpoints, and not the Asian focused checkpoints. Those, franquily, are only good in turning Asian women into baby looking monsters.

Generation parameters:

Clip Skip: 2
Best weight: 0.95

Sampler: DPM++ 2M Automatic/Karras, 35 steps

The model can make her bicolor red and black hair, but that's up to your luck so generate until you're happy.
