情緒藍色棚拍中的黑色波斯貓特寫肖像

The image should feature a black fluffy Persian cat with long whiskers, straight pointed ears, and golden eyes, with its head turned in a three-quarter profile gazing off-frame. He also is wearing a sparkling diamond collar. For the lighting and atmosphere, the entire scene should be lit with a cold blue-toned key light that catches the sheen of the coat and the wet texture of the nose. The background should fall to pure black with a deep shadow across half the face, creating a moody and cinematic low-key studio lighting effect with film grain.
