Out of curiosity what checkpoint and lora do you use to get these characters? They may be out of date (guessing SD1.5?), but for a TG style it's got a charm to it that no others have, and I can't find anything like it.
You draw them out and base them off of those? Like you made your own custom lora based off the drawings? Sorry if that's too personal. I've gotten into AI recently and honestly I'd pay good money to have the ability to do transformations similar to this in style.
