It's Ellie from Sprite Fright, a movie by the Blender Foundation.

I have trained the dataset on materials that are readily available to the public, or can be accessed on the Blender website.

Call her with elliesf, and use content tags like 3d, black hair, ponytail, earrings to create her look. Use different content tags to make this LoRA act like a style LoRA instead.
