At the top of the image, add: "Thanks for the gull-guard on my sandcastle!"

Ultra-high-definition 4K UHD photograph, portrait orientation. Golden-hour beach scene with accurate natural lighting and rich depth of field. Low, eye-level camera close to the sand (50mm lens look, f/2.8, ISO 100, 1/800s). Foreground: a meticulously sculpted sandcastle with crisp edges, shell trim, and a tiny red flag; grains of damp sand sparkle in the sunlight. Right beside it, a photorealistic seagull stands proudly, head slightly tilted with a cheeky, friendly “smile,” chest puffed like a vigilant guard. The gull’s feathers show lifelike texture and soft rim light. Nearby: a small plastic shovel half-buried and a few pebbles for scale. Background: gentle waves and horizon softly blurred, a couple of distant gulls bokeh’d in the sky. Color grading is warm and natural, with realistic shadows and highlights. On-image text styling: large, bold, clean sans-serif in bright white, centered at the very top with a subtle soft shadow for legibility; no other text, no logos, no watermarks, strictly photorealistic (no CGI or illustration).
