Create a highly realistic image of a Brazilian family consisting of four members—a child, two parents, and an elderly grandparent—all wearing sunglasses. The family is posing happily together in an outdoor setting with a warm, natural background. Each family member should be dressed in stylish, casual clothing, using a warm color palette with shades of red, orange, and yellow. The child is standing in front, the parents are standing beside each other, and the grandparent is slightly to the side, showing a multi-generational bond. The lighting should be soft and natural, enhancing the warm tones of their clothing and the sunny ambiance. Ensure the skin tones reflect a diversity common in Brazil, from light to darker shades, to showcase the diversity of the Brazilian population.
