I don't know what to say anymore. If you read my lora descriptions it seems I am going crazy.

I tried fixing from 1.0 that the tail would become part of the headgear, so hopefully this time it won't do that. So that it doesn't recognize it anymore as part of the head,

The tail is kind of hard to work with it seems. It might recognize the tail as part of the head

Trying something like "tail on head, tail above head" in the negative prompt
might mitigate that to some extent, or just removing "scythe tail"

This was mostly because the pictures that didn't have her tail end only showed that part. So the "Scythe" was only above her head.

Shiny Skin I have not tested

"Blue armor backlight"
This is specifically a light on her back, from official pictures of her back. So this would be specifically for pictures that are exclusively from behind probably. because it gives off the blue color of her hair, and some pictures it of her give off a faint light instead of the full color.
