A vibrant and colorful watermelon slice on a white plate, with a subtle sheen to emphasize its juicy texture, set against a soft pastel green background, under natural light with a slight warm glow, featuring the watermelon's distinctive green rind and pink-red flesh, with visible black seeds and a few droplets of water on its surface, capturing the freshness and sweetness of the fruit in a highly detailed and realistic style, with a shallow depth of field to blur the background and draw attention to the watermelon slice.
