Retrato en Balcón Art Decó al Crepúsculo

Medium-full vertical shot of [a Caucasian woman in her late twenties] standing on [an Art-Deco penthouse balcony] overlooking [a sparkling city skyline] at twilight. She has defined cheekbones, eyes half-closed in a serene expression, and deep auburn hair styled in thick waves cascading over one shoulder. She wears [a backless emerald-green silk satin evening gown with thin spaghetti straps and high side slits]. She leans casually with one hand on an ornate wrought-iron railing, holding a crystal champagne flute with visible condensation at chest height, head tilted back slightly. Polished marble flooring below reflects subtle ambient glow. Strong golden hour rim light from behind illuminates her silhouette and makes the gown edges glow, contrasting against deep twilight blue skies and warm streetlights below. Eye-level view with a slight low-angle tilt, shallow depth of field with creamy city bokeh, vintage cinematic color grading in rich tones of emerald, gold, amber, and navy.
