Create a detailed 3D anime-style teenage girl, 17 years old, with long flowing indigo hair tied in a high ribbon. Her eyes are bright turquoise with star-shaped pupils, symbolizing creativity. Outfit: a modern yet mystical battle dress – half school uniform, half magical attire, with brush-stroke patterns glowing faintly across her skirt and sleeves. Weapon: a giant magical paintbrush glowing with blue and white energy, tip dripping ethereal light-paint. She stands gracefully, like an artist ready to paint reality. Aura: swirling strokes of glowing ink around her, forming abstract shapes mid-air. Expression: calm but fierce, confident gaze. Background: floating brushstrokes glowing in the air like calligraphy.
