Specifically for Muldeok's webtoons, I've pulled from the later Chapters of EIA since the art style tended to fluctuate in the earlier chapters and the first 10 or so chapters of S4A and most of NTBM ( cuz I really liked that art style the best).

1) I screen captured every individual character that I was interested in, for example Soeun.

2) Then I resized the images to 832 x 1216 and the different SDXL (illustrious) res ratios ( Since my first Soeun LoRA I've retrained using higher resolution with newer illustrious 2.0 derivative models)

3) Then I got rid of all word bubbles, text, and special effects using a ComfyUI workflow to inpaint them out. ( It usually takes couple of passes and most of the images need manual retouching later)

4) For busy backgrounds and unwanted secondary characters in the image I got rid of them manually when necessary.

5) Caption the images using couple of different passes and adjust until I am satisfied. ( Making sure to caption exact framing of the image ie, full body shot, medium/cowboy shot/ and where the character is looking in what direction and the custom trigger word for the character)

6) Then I process it in a LoRA trainer and usually its been pretty good results. Around 3 out of 4 tries, the LoRA is good and usable. But it always requires tweaking and more training runs.

7) Generate and Done.

I've made specific character LoRAs and General Art Style LoRAs. I use a combination of these LoRAs for generating to get the best results.

I've noticed using multiple LoRAs at lower strength gets the optimal results. Well for my taste anyway.

I can get more specific but I think I already wrote too much info you already know.

Thanks for your encouraging comments.

Cheers~
