Sepia Pianist in Vintage Room

Create a vertical sepia-toned anime-style album-cover illustration of character name seated at an upright piano in a dim vintage room at night. The character is shown in three-quarter back view, slim and elegant, wearing a fitted black suit, black gloves, and polished black shoes; he has hair color tied in a low ponytail with loose bangs falling over his face. A small pet animal sits on his right shoulder. He is playing the piano with one hand while turning or holding a loose sheet of music with the other; an open music book full of handwritten staff notation rests on the piano stand. A light-colored coat is draped over the back of the wooden chair, hanging down almost to the floor. The room has dark wooden floors, heavy wall paneling, and tall glass windows or sliding doors on the left revealing a shadowy garden outside. Place exactly two warm light sources: one glowing oil lamp on a small wooden drawer cabinet beside the chair, and one faint warm outdoor lantern visible through the window. The mood should be quiet, melancholic, aristocratic, and intimate, like a late-night private performance. Use highly detailed fine ink linework, crosshatching, textured paper grain, muted sepia and black-brown palette, dramatic low-key lighting, realistic piano keys and wood grain, delicate facial features, and elegant manga illustration quality. No modern objects, no visible text except abstract musical notation, no watermark, no bright colors.
