A thoughtful anime-style illustration of a woman with long, flowing dark hair, her eyes gently closed or looking down, captured in a serene yet evocative pose, leaning against a dark, textured wall. She is wearing a simple black spaghetti strap crop top and matching high-waisted dark trousers or skirt. Her left arm is raised, with her hand elegantly resting behind her head. She has delicate golden hoop earrings and a thin necklace. The scene is dominated by dramatic, high-contrast cool blue lighting, with a single strong light source from the right casting brilliant, almost glowing highlights on her skin, hair, and clothing, while the rest of the scene is plunged into deep, mysterious shadows. The overall mood is quiet and introspective. The background is minimalist and dark, with subtle textures suggesting an aged or forgotten space. Sharp focus on the subject, cinematic lighting, digital painting, retro anime aesthetic.
