Create a watercolor and gouache artwork depicting a 20-year-old Vietnamese man with fair skin and blonde afro hair. The focus should be a close-up of his face from a frontal view. Use the softness and fluidity of watercolor for the gentler areas and the vibrant intensity of gouache to highlight the blonde afro hair and facial contours. The piece should convey a sense of balance between delicacy and boldness, with a harmonious combination of techniques that emphasize the uniqueness of his appearance and expression.
