To use the LoRA, you simply need to use the trigger word "iv4n0va", and with that, you will get most of the character's features. Additionally, if you want to achieve the artist's style for a 1:1 representation of the character, you can add the tags "painterly, sketch" to your prompt. (I have added an example in the preview.)
Notice:
Using a very long negative prompt might cause the yellowish skin tone to be lost.
To obtain certain characteristics of nudity, you must use the tags: inverted nipples, pink pubic hair
💡Just to clarify, none of the example images used Hires. fix, Adetailer, inpainting, or post-processing. This is so that what you see is what you get, so it's likely you'll see some common errors in image generation
