Kroma
The best version yet. It copies the style nearly perfectly and is not over-fit.
The LoRA strength can be pushed up to 1.5 to have stronger styling without too many side effects.
Kroma 0.3.1 OPD is most likely the best model I have ever touched for illustrations by a fair margin.
The LoRA works somewhat on Krea2, but you will get much better results on Kroma.
Anima
The Anima version of the LoRA does not work without the triggerword.
Anima already can do Muk's style decently. The anima only improves on it slightly if you don't use any style LoRA.
Though it fixes the white border issues that the base model has with the artist, as I cropped every image with white borders to fix it.
It also allows for LoRA pairing, as the model loses artist knowledge when using style LoRAs.
Description
Lora trained on 70 muk (monsieur) images at 1MP, using kohya-ss/sd-scripts with Adamw -2e04 LR constant for ~5k steps
There is a lot of room for improvement by changing the LR to something smaller at the end, adding a reg dataset, masking image with white background, ...
The captioning is also mediocre at best (JoyCaption makes a LOT of mistakes).
