I'm actually very satisfied with the results. Of course, there are some differences compared to LoRAs trained on multiple images:

It doesn’t work as well with overtrained LoRAs.

Most likely more stiff with facial expressions

Flexibility Settings

For more flexibility: Set strength to 0.7 and use the trigger word "ry4n".

For more likeness: Set strength to 0.85 and use it without "ry4n".

CFG Settings

Without any LoRAs: Set CFG to 2.7-2.9.

When using this with other LoRAs: Set CFG to 2.7-3.3. I usually keep it near 3. Really depends on what im doing.

Trigger Word Considerations

I include "light gray eyes" in the trigger, but sometimes it’s better not to use it because it can push the image too much.

Example: When using this LoRA with an ahegao LoRA, I don’t recommend including "light gray eyes" in the prompt.

Note: "Light gray eyes" wasn't actually a caption in the dataset—it’s just something that helps. https://civitai.com/models/1289206
