"Ultra-realistic full-body portrait of the woman from the reference image, now wearing a sleek black triangle bikini. She is posed confidently in a modern, luxury bathroom setting with marble accents and soft, ambient lighting. The shot should highlight a natural posture with focus on her midsection. Lighting is warm and cinematic, using a "golden hour" glow that casts soft, dramatic shadows to define her form. Captured on a Hasselblad X2D 100C, 85mm lens, f/1.8, professional DSLR quality with a shallow depth of field and smooth bokeh background. Texture is hyper-realistic, showing natural skin pores and a subtle, vintage film grain. 8K resolution, crisp details, --ar 3:4."
