Original character of russian artist StrAmp (https://t.me/teafeel). Character's name literally can be transliterated as Friday.
My attempt to train named character LoRA, took me 40+ training-hours and still not acceptable resemblance imo, even raised LR to 2e-4. If you want get more resemblance you can use flat color tag, although coloring will suffer.
Regularised, although weakly (0.38 prior loss weight).
