Isabelle LoRA trained on NovelAI with Kohya training scripts using the DAdaptAdam optimizer at 512x512 resolution. Works great, main issue is getting too many bells on her hair tie. Add (new leaf outfit) to your prompt to get her New Leaf outfit, add (hawaii shirt, white skirt) to your prompt for her New Horizons outfit. Should have wide compatibility with model mixes based on NovelAI, which is most of them.
