young woman portrait 3d-render

One subject: a single young woman centered in frame, positioned in the vertical center column with her head near the upper third and her décolletage occupying the lower half of the 2:3 portrait crop, filling most of the frame with minimal negative space at the edges. She faces the viewer with eye-level gaze and a calm, neutral expression, two loose space-bun hair knots, wispy fringe and stray tendrils catching light. A delicate luminous geometric symbol sits on the center of her forehead, and a narrow iridescent choker rests snug at the base of her throat. She wears a shimmering, sequined gown with narrow straps and a deep V that reflects tiny point highlights and soft specular blooms across the bodice. Back and rim lighting combine warm gold highlights behind the hair with cool teal fill on the shadowed planes to create crisp separation and subtle rim halos. Skin appears smooth with soft pores, faint blush on cheeks, tiny cosmetic sparkles across the upper cheeks and collarbones, and wet-looking lips with gentle sheen. Render as polished 3d-render portrait with photoreal material fidelity, precise hair strands, fabric micro-reflections, shallow depth of field and soft circular bokeh in the distant background.
