A painting of a man holding a child and a little girl

"Produce a photo-realistic image that captures the joy and love of a father with his children on a sunny day in the park. The father, approximately thirty-five years old, wears a blue button-down shirt and jeans. His smile is infectious as he plays with his children. One of the children, a six-year-old boy, has messy hair and is wearing a green T-shirt and shorts. He holds a colorful balloon with one hand and the other is holding his father's hand. The youngest daughter, aged about three, is on her father's shoulders, wearing a yellow dress and a sun hat. She laughs enthusiastically, stretching her arms to the sky. The surrounding park is full of green grass and colorful flowers. The sun shines brightly, creating soft golden reflections on the characters' skin and hair. The expressions of happiness and togetherness between the father and his children should be the main highlight of the image.
