Keep the character's facial features and posture unchanged, generate a fresh portrait: The person wears a beige short-sleeve shirt, paired with green overalls, wearing a green vintage newsboy cap. Wearing a red small scarf, slung with a green small crossbody bag, wearing white socks. Change the background to vermilion, the English "Happy Day" in calligraphy is placed at the upper right corner of the picture, the text is integrated around the character, and the lighting is soft and even.
