Masterpiece illustration of a low shot closeup featuring a child with a happy, cute face, sitting on the sand. The child has extreme detailed big eyes, blonde hair styled in pig tails, and is joyfully making a sandcastle with a plastic bucket. The scene is set under dramatic sunlight with lens flare, capturing the essence of a beach adorned with shells and glimpses of sea life. The image should be in 16k UHD HDR quality, highlighting the intricate details and vibrant colors. Avoid elements like cloned face, cross-eyed features, extra fingers, mutated hands, cropped images, low resolution, text, JPEG artifacts, or any form of signature, watermark, artist name, or trademark, ensuring a clean and immersive visual without distractions or out-of-frame elements.
