A 165cm tall catgirl with a slender curvy figure, cat ears slightly perked and a long tail gently swaying, wearing a skin-toned bikini, skin glistening wet from ocean spray. She stands in shallow waves, sea breeze blowing her long dark hair, bare feet on fine sand and foam. Golden hour side-backlight carves a rim light along her shoulder blades and waistline, 85mm portrait lens at f/1.4 with shallow depth of field dissolving the background sea into soft bokeh orbs. Natural HDR palette: amber warm light, deep teal ocean, sand-gold ground. 2.39:1 widescreen composition, medium format film grain texture, natural lens highlight rolloff, no plastic surfaces, no over-sharpening, cinematic atmospheric realism
