Create a polygonal artwork depicting a beautiful 16-year-old Nigerian girl with dark skin and short, straight white hair. The focus should be a close-up of her face from a frontal view. Use geometric shapes and distinct angles to capture her features with precision, highlighting the contrast between the depth of her dark skin and the brightness of her white hair. The piece should convey a sense of modernity and strength, with sharp lines and angular facets that create a visually intriguing and unique composition.
