Joyful woman in bikini on floating sand island

Photorealistic premium advertising photo of a floating rectangular sand platform against a soft gradient sky background transitioning from turquoise to warm coral. A tall palm tree leans in from the left edge. On the sand platform stands a joyful young woman in a pastel tie-dye bikini set, laughing with her head tilted back and one hand playfully touching her wind-blown hair, bare feet in the sand, white fluffy sandals beside her. Behind and around her, a dramatic ocean wave curls upward into a stylized decorative arc, crashing with realistic white foam and turquoise water texture. Surrounding her in mid-air, professionally composited with realistic lighting and matching shadows: floating beauty product bottles (spray mist, serum, lotion) catching sun glints, fresh orange slices, water droplets, and sunflower blooms suspended as if frozen in motion. Two seagulls fly across the upper sky, sun flare bursting from the top corner. A striped beach towel and a colorful beach ball sit in the foreground corner of the sand platform. Bold saturated color palette of coral, turquoise, sunflower-yellow, and golden skin tones, ultra-sharp realistic texture on skin, glass, water, and sand, glossy high-end commercial lighting, isolated floating-island composition on a seamless gradient background — fully photorealistic, no illustration, painterly, or cartoon style.
