Over-the-Shoulder Seaside Railing Portrait in Yellow Swimwear

Theme: A pause at the railing with the sea behind.
Subject: An adult woman in her twenties leans forward against a black seaside railing, back turned diagonally toward the camera, looking back over her left shoulder.
Appearance: Rounded brown eyes, fine nose, small short chin. Closed peach lips smiling toward the camera. High brown ponytail reaching below the chest, wispy bangs and small bead earrings. Bright cream and pale-peach skin; shallow natural facial and leg shadows.
Clothing and pose: Yellow bikini with white edging. Sheer white short-sleeved cropped top with yellow cuffs and a thin back tie. Platform sandals with white ribbon straps, slim wristwatch. Near elbow rests on the railing, hand lightly supporting the chin. Opposite forearm lies across the railing, hand extending left to grasp it. Legs slightly apart and elongated downward, both sandals on the floor.
Background and light: Black horizontal railing across the middle and broad plain white low wall below. Blue sea behind, white reflected light on the left, blue sky and small clouds above. Bright white natural light, retaining pale-peach skin tones distinct from cool blue sea.
Composition: Low rear three-quarter angle looking upward, legs large and turned-back face small above. Vertical 1121:1403. Include head and both shoes, subject on right. Large white-wall negative space at lower left, sea and sky above.
Texture: Soft seaside full-body photography. Preserve sheer white fabric, black railing and natural pale shading on long legs.
