his is a Textual Inversion I have created, this is mainly useful to improve your overall aesthetics and character anatomy.
I don't really have a suggested weight range for this, because it really depends on what model, lora and how complicated your prompt will be. These elements can effect how much weight you will need, I usually start without any weight just to see how much it effects my generations.
The images I have generated are purely just prompts and my Textual Invertion, I only switch around the checkpoint model to test the effect.
You can try more different variation and you can get even better results then I do, as this was just some testing.
