Update: There's now a new version for Illustrious, IL Official Art, trained only using official artwork of him, you can also use the tags greyscale and high contrast, if you want something like the black and white illustrations of Persona.
The Loras we have of Morgana don't generate him how i want him to look, so i decided to make a Lora of him myself, and i liked the results.
I recommend putting "nose" on the negative prompts if you don't want him with a nose.
