I messed up this LoRA as well but it turned out somewhat good.

Read bold text to get TLDR.

Its better at making the upper body of mimi sentry.

It will try to make it 3d and pixelated (sorry this is my fault).

It can make NSFW but it was mainly trained on SFW pictures.
I don't think it can make color variants or male version but feel free to try.

That's it thank you for your time and have fun.
