Warm and gentle portrait anime illustration

Create an exquisite anime-style illustration, from a top-down overhead view, depicting a cheerful young woman lying on soft white bedding, using a vertical portrait composition. She has hair tied in a high loose ponytail spreading to the upper right, with fine bangs and stray strands around her forehead; she has warm brown eyes, slender black oval glasses, fair skin, and a gentle slightly open smiling face. She wears a sleeveless white semi-transparent pleated shirt with a high stand collar and delicate pleats, paired with a light blue slim pencil skirt. Her left hand is raised beside her face making an OK gesture, her other arm gently crossed near her torso. Emphasize an elegant, friendly, and slightly playful expression, soft blush, delicate lines, glossy hair highlights, and soft watercolor-style shadows. The background is clean white bedsheets with faint creases and light blue-gray shadows, using high-key lighting, soft diffused shadows, a bright and airy atmosphere, no text, no watermark, no extra characters, no cropping of face or hands.
