1st pass on Karin Frost-Fang, the junkie drunky knife wielding dress ruining scumbag nord assassin OC from my fanfics and my avatar. Why Karin? Well, it's like how MD Geist was the spokes mecha for US Manga Corp all those years. Sometimes the character that stands out to you just happens to be the nihilistic psychopath.
So this was my first ever lora, more excuse making down below, but first, hey Johnny, how do you use this thing? Why didn't you test this thing? I don't know how to test it 'cept to put it out on civitai! So I'd recommend using it at low settings or mixing it up with some powerful style loras, its got its flaws for sure but depends on what you're going for. It seems like it does better if you either really lean into realism/3d or go with a more cartoony/anime model. You may even find you get better results in draft mode, if you don't typically break that out I recommend it.
Her default look is mostly:
A hacked off/torn up blue dress similar to Ysolda wears.
Blue bandana over headband
Holding a knife
A nasty grin
It also seems to want to tend towards a real scratchy sort of messy style and blues and greys, which I like, but might get old, so I'd put stuff like sketch, bandana, evil, grin, etc in negatives if you want to tone that down.
In fact, I'd put the bandana in either the prompts or the negative or it tends to give you like a half a one. I got her breasts right though, I'm really proud of those. She does have a prettied up makeover look that you might be able to get to show up with things like "pretty", etc but I think I messed that up and need to include better tagging and more samples next try. Also it seems to really go overboard if you're trying to make her crazy/psychotic, so keep that in mind.
I had NO idea what I'm doing training wise, this is my first lora and I trained this one on the very sparse amount of commissioned work on her and various AI. I also don't have a home rig like you kids with your bebop jazz, I didn't know what I was doing about tagging and consistency so we'll get the outfits and looks and all that fun competent stuff next revision.
