Created as my first try at LoRA training. I usually create images of Elves, however, depending on the art style, model, or other LoRA at play I find that models tend to draw pointed ears as follows;
Upward ticked
Flat against the skull/side of the head
Narrow

It seems like anything other than this (at least for me, is a happy accident. I trained this on a range of character profiles, mostly line art with a bit of realism mixed in too, in which the characters have horizontal outward pointing ears, or, downward sloping ears.

Think of it as pushing towards Frieren's ears... without the Frieren.

Iv sampled a few different Epoch's and like where this one sits, weights 0-1 will produce more intense ears as one might expect... there is a little style bleed of line art, but it can still help you get flatter, horizontal ears.
Tested it with a few different models and LoRA combined and it seems to play nicely.
