Realistic Long-Haired Cat Portrait

Create a highly realistic studio portrait of a long-haired animal subject facing forward in a tight head-and-chest crop, centered in the frame and looking directly at the viewer with a calm, slightly serious expression. The cat has fur color and pattern, with a white muzzle, white blaze running up the center of the forehead, fluffy white chest, darker gray cheeks and crown, and long layered fur with visible individual strands. Emphasize large upright triangular ears with pink inner ears and fine ear tufts, bright eye color eyes with sharp vertical pupils, a small soft pink nose, and long white whiskers extending outward on both sides. Use photorealistic animal photography style, extremely detailed fur texture, natural soft studio lighting, shallow depth of field, crisp focus on the face and eyes, subtle catchlights, and a smooth dark background color backdrop with gentle vignette. Vertical portrait composition, square-to-near-portrait crop, no accessories, no text, no watermark, no human elements.
