I apologize in advance, as I only have a single reference image to work with. Tragically, the creator of this character—my best friend's girlfriend—passed away in a car accident, making it impossible to get any more material. I want to train a model of her character for my friend. I know this won't fix his grief, and I'm not even entirely sure it's the right move, but I want to offer him at least a temporary moment of comfort.

The goal is to create a model that can generate 2D images to serve as a chatbot avatar. It needs to be flexible enough to handle default expressions (happy, angry, sad) and specific poses (like a fighting stance or reading a book).

I tried training it myself, but the character's hairstyle is giving me a headache and I am making zero progress. Thank you for reading and for any help you can offer.
