**{character['name']}** (*{character['series']}*) is captured in a professional Ultra HD 16K (15360x8640) RAW photograph, set in **{setting}**, the ambiance filled with sensory elements. Her flawless cosplay features **{character['hair_color']} hair styled {character['description']}**, accented by **{character['eye_color']} eyes**, cascading over a **{lingerie_color} lace thong** and matching transparent lace bra. **Thigh-high stockings** with **{stocking_detail}** accentuate her legs, paired with **{heel_detail}**. The character is posed in a **{pose}**, her **{expression}** directed at the viewer. Shot from a **low-angle (worm’s eye view)** using a **Canon EOS R5 Cine RAW** with a **Canon RF 85mm f/1.2L USM lens**, the composition emphasizes her dominance and the sensual details of her lingerie. **ARRI SkyPanel S360-C lighting** creates soft, flattering illumination, enhancing realistic skin texture and fabric sheen, while **DaVinci Resolve color grading** adds vibrant, cinematic tones. The full vertical frame (knees to head) ensures no cropping, with perfect depth of field and subtle bokeh background.
