Emerald Couture Seasonal Portrait

Create a painterly high-fashion portrait of a single elegant woman representing the {argument name="season vibe" default="winter emerald mood"} palette. Vertical 3:4 canvas, waist-to-knee crop, dramatic studio lighting. The woman stands in a graceful contrapposto pose with one hand resting on her waist, wearing a flowing deep {argument name="dress color" default="emerald green"} couture gown with a plunging V neckline, wrapped bodice, layered drapery, long translucent chiffon sleeves, and subtle gold highlights in the folds. Her {argument name="hair color" default="dark teal-black"} hair is shoulder length, glossy, and wind-swept to one side. Place her in front of an abstract impasto oil-paint background made of broad palette-knife strokes in teal, forest green, dark blue, olive, charcoal, and small ochre accents. The overall mood should be moody, luxurious, artistic, and editorial, blending photorealistic fashion photography with visible painterly texture. Keep exactly one human figure, no text, no logos, no jewelry emphasis, no extra props, Show every face clearly with natural, detailed facial features, garment, color palette, and brushwork.
