Create a polygonal and gouache-style artwork depicting a beautiful 45-year-old Paraguayan woman with dark skin and loose, curly hair. The focus should be a close-up of her face from a frontal view. Use polygonal geometric shapes to sculpt her features, creating a bold and modern angular structure, while gouache brings depth and softness to the textures of her skin and curly hair. The composition should balance the precision of the polygonal style with the vibrant richness of gouache colors, highlighting the strength and elegance of her expression.
