Create four full-body stylized 3D cartoon images of a middle-aged black man with a transparent background, suitable for use in a PowerPoint presentation. The character should be consistent in appearance across all images and rendered in a Pixar-like style using Arnold Maya or toon Keyshot render. The rendering must be of high quality, featuring cinematic lighting, sharp focus, detailed textures, detailed skin, a clay-like finish, and bokeh effects, all in 8K resolution. The man has a broad build but without a belly or muscular physique. He wears modern black glasses and has very short gray hair, styled to the right on top and shaved on the sides. His skin tone is dark brown with a warm undertone, and he has two prominent vertical wrinkles on his forehead between his eyebrows. His beard is trimmed and sparse, with more white hairs on the chin and the rest being dark gray. The man has hairy arms and does not wear any accessories or jewelry, except for a black smartwatch. He is dressed in an oversized black t-shirt and dark gray pants without a belt. Each of the four images should feature the man with a different facial expression: A friendly but neutral expression (not smiling). A slight smile. A thoughtful or pensive expression. A surprised or curious expression. Ensure that the character's appearance remains consistent across all images, with only the facial expressions changing.
