Princess Concept Art in a Medieval Castle

An elegant regal princess in the grand hall of a medieval castle, concept art style, cinematic, high detail, semi-realistic painterly. Three-quarter view, slight low angle, standing center stage. She wears a flowing emerald green velvet gown with gold embroidery, a trailing train, and a delicate crystal crown. A silk cape lined with fur drapes from her shoulders; ornate gold jewelry; she holds a slender scepter. The hall features towering stone arches, stained glass windows casting colored light, banners with a crest, heavy wooden doors, torches along stone walls, and rich tapestries. Atmosphere with warm amber torchlight and cool blue shadows, dust motes in sunbeams, textures of stone wood metal and fabric. Lighting is cinematic with volumetric light, soft rim light around her silhouette, shallow depth of field focusing on her face and gown. Color palette of golds, deep blues, forest greens with crimson accents. Mood is regal and enigmatic with a touch of fairytale realism. Composition a wide angle interior shot with pillars receding toward a distant throne, hints of heraldry on carpet and banners.
