An adult female is observed floating on her back in calm, greenish-blue seawater in Phú Quốc, Vietnam. She wears a dark bikini top and a light-colored baseball cap with a red emblem on the front. Her body is supported by a two-piece blue flotation device positioned under her upper back/arms and lower back/legs. Her arms are extended, and her bare feet are visible at the water's surface. She appears to be looking upwards and slightly to her left. The water's surface exhibits subtle ripples. A small, dark, spherical object is visible on the water in the middle distance. The scene is set under a blue sky with scattered white clouds, featuring distant landmasses along the horizon.
