Create an ultra-realistic full-body lifestyle portrait in a 4:5 vertical aspect ratio. Use the uploaded image strictly as the ONLY face reference. Composition & Camera: Full-body shot, head-to-toe visible with no cropping. Subject positioned slightly off-center, leaning casually against a wooden railing on a narrow boardwalk. Shot at eye level with an 85mm lens look, shallow depth of field for strong subject-background separation. Pose & Expression: Relaxed leaning pose with one leg slightly bent and foot resting against the wooden plank. One arm resting on the railing, the other relaxed near the waist. Head turned sideways (away from camera) with a soft, thoughtful expression. Natural posture, effortless and candid. Outfit & Styling: Light sky-blue button-up shirt with sleeves rolled up to forearms. Off-white loose trousers with a soft, breathable texture. Clean chunky white sneakers. Accessories include a black Casio-style sports watch and frameless sunglasses subtly hanging from the shirt. Environment & Background: A tropical mangrove setting with clear, shallow turquoise water visible beneath the wooden boardwalk. Detailed mangrove roots emerging through the water. Background softly blurred but still recognizable, with lush green foliage and natural depth. Lighting & Mood: Warm golden-hour sunlight coming from the side/back, creating soft highlights on the face and rim lighting along the edges. Gentle shadows, natural skin tones, and a cinematic glow. Light reflects subtly off the water surface. Technical Details: Ultra-realistic photography, 8K resolution, high dynamic range, natural skin texture with visible pores. No CGI, no artificial smoothing. Sharp focus on subject, soft bokeh background.
