I had a go at making a Lora for A2. I'm going to come back to this and improve on it because A2 is a character from one of my favourite games of all time. I plan on doing a Kaine one too, since they are similar characters.
I think in terms of quality, it's pretty good. It does the eyes great in particular from my experimentation but getting her moles accurate takes some rolling of the dice (I'll likely need some more face close ups in the dataset).
However, it's versatility isn't great but you can get some outfits like a kimono for one example. With some prompting I think you can work around and get some nice generations regardless.
Please do leave a comment if you have any thoughts!
TIP: ADetailer is amazing for faces, I 100% recommend it!
