"Photorealistic portrait of an elderly Indian man, late 60s, breaking a walnut with his teeth, medium-dark skin tone with wrinkles that show age and wisdom, short gray hair and a neatly trimmed beard, intense focus on his expression as he bites down on the walnut, hands holding the walnut, natural lighting highlighting the texture of his skin and the walnut, traditional Indian kurta, rustic background with soft blur, detailed close-up of his teeth and the walnut shell cracking, promoting strength and health, high-quality image perfect for social media or advertising."
