Photorealistic vertical portrait of a fit adult blonde woman wearing a vivid cobalt blue string bikini, standing before a softly blurred waterfall and lush tropical foliage; long hair pulled into a high ponytail with a few loose strands framing her face, subtle natural makeup, sun-kissed warm skin, defined collarbones and toned midsection with a small belly-button ring. Frontal three-quarter pose, shoulders relaxed, direct soft gaze to camera with a confident, serene expression and slight half-smile. Golden-hour warm rim lighting, shallow depth of field with creamy bokeh, high-resolution detail, crisp texture on skin and fabric, cinematic filmic color grading emphasizing saturated blues and warm skin tones, gentle contrast and soft skin retouching, vignetting for focus, magazine-style beauty photography composition, vertical crop from head to upper thighs, tasteful and elegant, emphasize natural environment and the interplay of light on water and skin.
