Beachside Heartfelt Moment

Create one vertical 9:16 image: a lock-screen wallpaper photograph of the couple in the attached photo, sitting back to back on the sand with turned smiles and finger hearts beside their outer cheeks.
FACE MATCH - TOP PRIORITY: The attached photo is the identity source only. Recreate both exact people, never lookalikes. For each face preserve the same hairline, hair colour and texture, brows, eye shape and spacing, nose, lips, jawline, chin, cheek width, skin tone, any mole, freckle, scar or dimple in its exact place, and for him his own facial hair. Never beautify, slim, smooth, age or restyle either face. Take nothing else from the photo - not its light, expression, clothes, pose or background.
FRAME: Vertical 9:16. Reserve the top forty-five percent as pale empty sky for device clock overlays added later. Hair, fingertips and the low horizon stay below it. Camera at seated chest height, four metres away, 50mm lens; frame both from crown to bare feet, faces turned toward the camera.
BODY: Two real adults, each with two arms, two hands, two legs and two feet. Each hand has four fingers and a thumb; unused fingers curl naturally side by side while the named digits form the heart gesture. Every limb connects to its owner and does only its assigned action. Heads in true scale, adult shoulders and natural hand sizes; cropped limbs continue outside the frame.
SCENE: A quiet beach with smooth sand and a narrow blue sea strip behind the seated couple. Horizon below the upper band. No shells, umbrellas, birds, buildings or visible sun disk.
WEARING: Matching light-wash denim shirts over white ribbed tees and ivory linen trousers with rolled hems. Her shirt is tied loosely at the waist; his sleeves are rolled. Both barefoot. Denim stitching and soft linen creases stay visible; no accessories or lettering.
POSE: He sits on the left, she on the right, backs touching lightly, knees bent outward in opposite directions. Each turns their torso slightly toward the lens. His left palm and her right palm brace on the sand beside their hips. His right hand and her left hand rise beside their outer cheeks, index tips crossing thumbs into small finger hearts. Toes rest naturally on the sand; necks never twist beyond three-quarter view.
GAZE: Both look into the lens, laughing at their synchronized pose. Their eyes gently narrow with joy and their smiles show natural teeth. Keep both faces equally sharp and recognizable; their heads turn comfortably without hiding the far eye.
LIGHT: Key: soft morning sea light camera-left, neutral and diffused through thin cloud. Fill: pale sand bounce one stop below the key reaches both faces. Keep catchlights clear and skin true. The sky remains softly exposed below facial brightness, with denim and white fabric texture intact.
PHOTOGRAPH: A true photograph on a real camera, not an illustration or 3D render: natural uneven skin tone, individual brow hairs, realistic hair strands, honest fabric weave, soft lens grain, real skin texture scaled to the crop, never retouched smooth. White balance stays neutral to the key.
TEXT: No text, logo, watermark, letters, numbers, clock, date, battery icon or status symbol. Clothes and scenery have no lettering. Hearts come only from their physical gestures; no graphic hearts, stickers or interface. The upper band stays empty.
FINAL CHECK: Both faces are the exact couple in the attached photo, every feature matching, lit by the soft morning sea key; if any feature differs, it is wrong. Two intact adult bodies, limbs and hands exactly as described. Vertical 9:16, no text.
