Idea is to create a "vertical cut in" of characters at longer height generations (examples use 512 x 768). Maybe for a team attack? ;) Pretty straight forward. Activation word is vcutin but not 100% necessary. Recommend on anime models. Start with .80 weight and go from there. Can play with facial expression but complicated ones may not work. Example of things that work are devious smile, sly smile, straight face, angry, etc.
Example Prompt:
<lora:vCUTIN-18:0.8> a detailed character portrait vcutin, close up, detailed face, smug face
<lora:vCUTIN-18:0.8> a detailed character portrait vcutin, detailed face, sly smile
