Sepia Pianist and Hamster

Create a vertical monochrome/sepia anime-style album-cover illustration of {argument name="character name" default="a slender young pianist"} seated with their back mostly to the viewer at a glossy black grand piano in an old European study. The pianist has {argument name="hair color" default="pale silver-white"} tousled medium-length hair tied into a small low ponytail, wears a fitted black suit, and is mid-performance with both hands on the keys. A small {argument name="animal" default="hamster"} sits on the ornate music stand of the grand piano, facing the pianist like a tiny attentive audience. The room is richly detailed and realistic: tall leaded-glass windows on the left with sheer bright daylight streaming in, heavy curtains, dusty sunbeams, dark wood floor, wall molding, framed pictures, a coat stand, and a tall bookcase packed with books behind the raised piano lid. Include exactly 1 pianist, 1 grand piano, 1 piano bench, 1 hamster, 2 tall window panels, 1 large bookcase, 1 foreground teacup and saucer, and 1 cluttered writing desk corner with pens and stacked books. Use dramatic chiaroscuro lighting, strong backlight from the windows, reflective black piano surfaces, fine line-art detail blended with painterly realism, muted sepia grayscale tones, melancholic intimate atmosphere, cinematic composition, high detail, no text, no watermark.
