Remember to use the trigger word choiyewon. Use LORA weight 1 and Hires fix with latent bicubic antialiased, 20 steps, 0.4-0.6 denoising strength, and 1.25x upscale. I've used the DDetailer extension for pretty much every example picture.

Version 2: You can use V2 with the same settings (as well as DDetailer to help) but you can also try mixing the two versions, ie, use "<lora:arinOTW_v2:0.5> <lora:arinOTW_v1:0.5>"
