Create a gouache and polygonal-style artwork depicting a beautiful 25-year-old American woman with dark skin and short, curly green hair. The focus should be a close-up of her face from a frontal view. Use the rich texture and vibrant colors of gouache to highlight her features and green hair, while polygonal geometric shapes bring angular structure and modernity to the composition. The piece should convey a sense of boldness and innovation, blending the softness of gouache with the sharp precision of polygonal style.
