Create a highly detailed, hand-drawn 2D anime-style illustration of a beautiful young woman sitting on the floor while talking on a vintage yellow landline telephone. Character: A young woman with long, glossy black hair, straight bangs, large expressive dark eyes, rosy cheeks, delicate facial features, and a playful, slightly surprised expression. Her hair is styled with a bright orange hair clip on one side and small silver hoop earrings. Pose: Sitting casually on the floor with her body slightly leaning forward. She holds the yellow telephone receiver against her ear with one hand, looking sideways with a curious expression. Her other arm rests naturally on her bent knee. The red coiled telephone cord extends across the floor and around her body. Outfit: An oversized cream-colored long-sleeve shirt layered over a teal blue top, with natural fabric folds and loose sleeves for a cozy, casual aesthetic. Telephone: A classic vintage mustard-yellow telephone receiver with a matching red coiled cord, rendered with detailed highlights and smooth glossy surfaces. Background: A simple, warm off-white textured background with subtle paper grain and minimal environmental details, keeping the focus entirely on the character. Art style: High-quality Japanese anime illustration, modern manga aesthetic, clean expressive linework, soft cel shading, warm pastel colors, subtle highlights in the hair, detailed facial expressions, natural anatomy, delicate blush, and a polished editorial illustration finish. Composition: Vertical 9:16 portrait, medium close-up to three-quarter view, character positioned slightly off-center, with the telephone cord creating a natural visual flow through the composition. No text, no watermark, no additional characters. Ultra-detailed, high-resolution illustration.
