Square anime-style album-cover illustration of [three elegant young male classical musicians] performing in an ornate antique salon. Exactly three seated musicians: on the left, a brown-haired cellist in a formal black suit playing a cello; in the center, a silver-gray-haired violinist with a long braid seated slightly forward playing a violin; on the right, a tousled white-haired violinist seated at a slight diagonal playing a violin. All three wear tailored black suits, crisp white shirts, and dark ties, with slim silhouettes, delicate bishōnen facial features, and serious, focused expressions. Setting: a richly decorated vintage European parlor with tall sunlit windows on the left, sheer lace curtains, damask wallpaper, carved wooden chairs, a mantelpiece, candelabras, framed floral oil paintings, and an antique patterned rug. Palette and style: sepia monochrome with warm beige, ivory, rich brown, and black ink tones, intricate manga line art, painterly shading, dramatic soft window light, and subtle instrument wood grain. Composition: intimate close crop, with the cello occupying the lower-left foreground, bows creating dynamic diagonal lines across the frame, melancholic chamber-music atmosphere.
