General info
My first attempt at creating a Lora. Recently hopped on the SD bandwagon and learning as we go along.
Which version should you use?
There are 2 versions. V_portrait for most consistent likeness, but v_flex if you want to try and get a shot from a bit further away. You might get a good one.
Performance
At specific facial angles from up close it manages to capture her likeness fairly well. Quickly breaks down from farther away or odd side/back angles. Basically if it's from far away enough that you can see below the chest, the likeness usually just isn't there (or maybe I just can't bring it out).
Strength
Starts convincing me at strengths 0.7 and up, but your mileage may vary. Sometimes I get a lucky roll with 0.5 strength.
Side notes
In a lot of the training images she was wearing a choker/necklace. Add choker, necklace to your negative prompt to try and mitigate this if you don't want them in your images.
She might look a bit young sometimes, because some training images are from when she was younger.
If your images don't turn out exactly like the sample images, even when copying the generation data, it might be because you're running Stable Diffusion with xformers enabled. This sacrifices reproducibility on the same seed for faster image generation. Sample images were generated with xformers disabled.
Description
Trained on photos cropped from head to shoulder/bust height. More flexible and interferes less with the rest of your prompt. Likeness is a bit of a hit or miss though, but keep rolling and you might get a few ones that look a lot like her.
FAQ

how many images? I see 1875 steps but is that for like 187 images with 10 repeats or is that like 50 images with 40 repeats.
I see you had 128 dim/alpha
What about LR?
SD 1.5 base model I can see
Any other info about the training?
I followed this tutorial: Creating a LoRA weight using kohya_ss GUI, part 1: Dataset creation and preparation - YouTube
I used more images though. The final dataset contained 75 images.
