Style LoRA based on the works of Rhineheim, an artist who did some nice lingerie and consentacles art, but hasn't been active for almost six years now. Seems he purged all but one of his tentacle artworks from Pixiv, but they're still around on Danbooru.

It's not the most distinct style, but comparing it to without the lora and trigger does show a noticeable difference (see last showcase image).

IL_v1:

Trigger is Rhineheim

Works best at a strength of 0.9 with latent upscaling, may need 0.95 or 1.0 without upscaling. Use at about 0.7 when combining with concept LoRAs to improve compatibility.

Upscaling by 2x is a bit prone to adding extra fingers, unfortunately.
