In my opinion, in terms of likeness, Yena > Yuri > Chaewon. This was more of an experiment in multiple concepts for me. If nothing else, you can think of it as a Yena LORA as decent as any of my other ones.

• Yena: Use the trigger word choiyena. Use LORA weight 0.9-1. It works with LORA weight 1, but sometimes has funky colors, so you might need to reduce the LORA weight to 0.9.

• Chaewon: Use the trigger word kimchaewon. Has exaggerated features, so you can use a lower LORA weight 0.7-1 or add 0.1-0.4 weight of KoreanDollLikeness LORA (not the best solution but oh well).

• Yuri: Use the trigger word joyuri. Similar to Yena, use LORA weight 0.9-1.

I used Latent Couple for the group picture. As per usual, I used Hires fix with latent bicubic antialiased, 20 steps, 0.4-0.6 denoising strength, and 1.25x upscale.
