FLUX prompt: A photorealistic full-body shot of a fit

A photorealistic full-body shot of a fit, tanned woman lying supine on a beach towel under intense midday sun. She is wearing dark aviator sunglasses with silver frames and plain white low-waisted bikini bottoms featuring thin straps. Her arms are raised behind her head in a relaxed pose, exposing her torso which features distinct, wavy shadow patterns cast by an unseen slatted structure or umbrella above. The shadows create a rhythmic, curved texture across her chest and abdomen, contrasting sharply with the bright highlights on her skin. She has long brown hair fanned out around her head and a subtle, serene expression with slightly parted lips. Her skin appears glistening with oil or sweat, catching the light to emphasize muscle definition and body contours. The towel beneath her features broad stripes in earthy tones of terracotta orange, navy blue, and cream. The background consists entirely of textured sand dunes with deep, sharp shadows indicating a harsh, direct light source. The image is captured from a high angle looking down at the subject. The lighting is cinematic and dramatic, creating high contrast between the sunlit areas and the deep shadows. The color palette is warm, dominated by golden browns, tans, and blues. The texture of the sand in the background is soft and rippled, while the woman's skin looks smooth yet detailed with pores and fine hairs visible. Sharp focus on the subject's face and torso, with a shallow depth of field that slightly blurs the distant sand dunes.
