Create a lineart illustration Setting: Hellen revealing her true nature, with a feline, demonic expression. Details: This illustration can focus on Hellen's face, showing her transformation from a careless expression to one that reveals sadness, hatred, and vengeance. The combination of feline and demonic features should be subtle, but enough to show her hidden essence. The surrounding environment can be dark, with the light highlighting only Hellen's face and the spirits that surround her.
