I'm pleased to announce that I've completed training my own Lora. The model is made by me from scratch. It's still being tested, but I invite you to try it out for yourself. It's perfect for various proportions; it all depends on what you pair it with and how powerful your Lora is. I recommend pairing it with a Lora from a lineart or sketch. If you sometimes get a chibi you didn't request and don't want it to stay, you can enter the following into the negative prompt: mini_person, tiny_person, extra character, mini_clone, extra chibi, super deformed.
That should help. :) The mini chibi isn't bad sometimes. I think it only appears with specific Lora combinations, because it's only happened to me twice. (Fixed)
Interesting: I think it works very well with the Otome v2 model and Vixon's Noob Illust Merge.
