Create a gouache artwork with color splashes, depicting a 20-year-old Bolivian man with dark skin and short, red afro hair. The focus should be a close-up of his face from a frontal view. Use the vividness of gouache colors combined with dynamic splashes to capture the vibrant energy of his features, highlighting the contrast between the depth of his dark skin and the visual impact of his red afro hair. The piece should convey a sense of boldness and dynamism, with expressive brushstrokes that bring the composition to life and enhance the uniqueness of the portrait.
