Use the uploaded portrait only as the identity and hairstyle reference. Accurately preserve the person’s real facial identity, face shape, skin tone, natural features, hairstyle, and overall real-life appearance. Do not copy the original clothes, background, lighting, pose, or image quality from the uploaded portrait. Create a dreamy summer coastal poster in a soft blue Japanese / Korean youth magazine style. The background is a bright seaside road with a clear blue sky, large fluffy white clouds, distant ocean, street poles, wires, road markings, and a clean sunny atmosphere. The whole image feels fresh, nostalgic, cute, and cinematic. Place a large white Polaroid photo frame in the center, slightly tilted, with the same person inside the Polaroid photo. The person is standing outdoors near the seaside road, wearing a simple stylish summer outfit, natural pose, one arm raised slightly, soft relaxed expression, long hair gently glowing in sunlight. The inner photo should look like a slightly overexposed film snapshot with soft blur, sunlight haze, realistic skin texture, natural body proportions, and candid vacation energy. Add clean white hand-drawn doodle decorations around the frame, such as simple brackets, arrows, small birds, curved lines, and playful sketch marks. Keep the design minimal and tasteful, not messy. Replace all existing text with better English text: Top handwritten text: “Blue Sky Diary” Bottom text on the Polaroid frame: “Stay Sunny” Use soft handwritten typography, clean and readable, matching the dreamy summer poster style.
