"I created this out of a limited training set."

(Well, I guess with V6 is not as limited as it used to)

"It is meant to be used inside the Detailer/Adetailer prompt specifically. Showcase pictures also include positive/negative embeddings."

(As you can see by the demonstration images, It works perfectly fine in the main prompt)

Running into mismatch issues is a real possibility, Adjusting LoRA strength and/or Denoise often resolves the issue.
