Korekta Postawy w Szkole Baletowej

Cinematic film still of a female ballerina in her [early 20s] with an elegant, athletic build, standing en pointe in focused rehearsal. Her eyes are lowered in deep concentration, refined facial features illuminated with porcelain sheen, subtle muscle definition along her neck and shoulders, and a classic ballet bun with backlit wisps of loose hair. She wears a form-fitting [muted ivory] practice leotard, showing perfect vertical alignment and physical tension during technical correction, with the polished shoe of her choreographer subtly visible between her feet. Set in a [vintage rehearsal studio] with [dark wood-paneled walls], a large wall mirror capturing her reflection in symmetrical balance, and a wooden barre in the soft-focus background. Shot from a low angle on an 85mm lens with soft bokeh. Directional warm Rembrandt key lighting from a single side lamp casts a golden amber glow and deep, velvety shadows across the detailed fabric textures, polished wood grain, and satin sheen of her pointe shoes.
