Create a hyper-realistic 4K image of a beautiful 20-year-old Korean woman inspired by a darker, 'corrupted' version of this character, while retaining her gradient blue-to-purple hair. Her hair is styled in sharper, more defined waves, giving her a bold and intimidating appearance. She wears a darker, celestial-themed outfit with metallic accents and sharp edges, creating an aura of a fallen celestial queen. Her large, piercing blue eyes have a cold and intense gaze, with darker makeup and shadowing around the eyes to add to her mysterious and powerful presence. The background is a gradient of deep purples and midnight blues, enhancing the eerie, otherworldly atmosphere. Lighting should highlight her smooth skin, sharp features, and intense expression, crafting a lifelike, captivating portrait that emphasizes her darker, more enigmatic personality while keeping her original hair color.
