    // Sample output:

    // The image displays a single, vibrant **starfish** set against a plain **white background**.
    // 
    // Here's a more detailed description:
    // 
    // *   **Object:** A single starfish.
    // *   **Shape:** It has the characteristic five-pointed star shape, with each arm tapering slightly to a rounded end. The arms appear somewhat plump and substantial.
    // *   **Color:** The starfish is a beautiful **warm, golden-orange color**, with subtle variations in hue that suggest natural texture and depth. Some areas might lean a little more yellow, while others have a slightly richer, deeper orange tone.
    // *   **Texture:** Its entire surface is visibly **textured**, covered in numerous small, raised bumps or granular patterns. These details are consistent across all the arms and the central body, giving it a rough, almost sandpaper-like appearance, typical of a real starfish.
    // *   **Lighting & Depth:** The lighting on the starfish highlights these textures, creating subtle shadows in the crevices between the bumps and making the object appear distinctly three-dimensional and lifelike. The light seems to come from above, casting gentle shadows that define its form.
    // *   **Background:** The starfish is isolated against a pure white, featureless background, which makes it stand out prominently as the sole subject of the image.
    // 
    // Overall, it's a clear, well-lit photograph of a textured, orange starfish.
