Minimalist Mixed-Media Eye Illustration

Create a minimalist mixed-media illustration that combines a simple black line drawing of a detailed human eye with eyelashes and eyebrow with a real-world object, a [marble color] glass marble with swirling patterns, strategically placed to represent a key element in the artwork. The marble becomes the eye's vivid iris and pupil. The object should be seamlessly integrated and visually meaningful in a mesmerizing way. Use a clean, [background color] or off-white background for contrast, and ensure the lines are clear and the object stands out naturally.
