Flat-Coated Retriever Portrait in Winter Window Light

A Flat-Coated Retriever rests on a textured fabric sofa, its jet-black coat displaying distinct sheen where cool north-window light strikes the shoulder and muzzle. The dog's ears fold neatly against a head turned slightly toward the glass, while heavy winter curtains frame the opening with thick, unblinking folds. Bright midmorning sky pushes diffuse illumination through the window, casting soft reflections on a nearby table surface that sits just out of the main focal plane. Negative space surrounds the animal on the sofa, emphasizing its calm posture within the domestic interior of a Taiyuan home. A thin line of light traces the curve of the dog's shoulder.
