Elderly Biker on Eggplant Motorcycle

Create a hyper-realistic street photograph of {argument name="rider description" default="an elderly Japanese biker with slicked-back white hair, a gray goatee, black sunglasses, black leather gloves, black boots, dark jeans, and a black embroidered leather jacket"} sitting confidently on a bizarre custom motorcycle built entirely from vegetables, inspired by a modern Obon spirit horse. The motorcycle should look mechanically believable but organic: use exactly 2 giant glossy purple eggplants as the main body pieces, with one long eggplant forming the fuel tank and seat area and one upright eggplant forming the oversized front headlight cowling; use exactly 2 oversized dark-purple eggplant wheels, each covered in small round vegetable studs like tire knobs; use green cucumbers, zucchini, bamboo-like stalks, and eggplant stems as the handlebars, front forks, frame tubes, exhaust pipes, engine parts, spokes, foot pegs, and suspension. Add cut cucumber ends and green vegetable cross-sections as small mechanical details, bolts, caps, and pipe openings. The rider leans forward with both hands gripping the cucumber handlebars and one boot planted on the asphalt, giving the scene a cool outlaw biker attitude. Set the scene on a realistic urban Japanese street with a beige concrete wall, metal railing, sidewalk, and a partially visible parked black compact car in the background. Use natural overcast daylight, shallow depth of field, documentary realism, detailed vegetable textures, glossy eggplant skin, rough cucumber bumps, cinematic contrast, and a slightly low eye-level camera angle. No text, no watermark, no cartoon styling.
