A photorealistic studio photograph of a Sphynx cat, designed as a vertical smartphone wallpaper (aspect ratio 9:16), in the style of high‑end professional studio product photography. Subject: The cat is an exact replica of the uploaded reference: same breed, fur pattern (or lack thereof), eye color, facial structure, and all specific features preserved. The Sphynx cat is sitting firmly on the floor in a relaxed, stable posture; hindquarters and front paws resting naturally. Head tilted far back, chin pointing upwards; eyes gently closed in a joyful, relaxed expression (as if feeling the music); mouth slightly open in a contented manner.
