Young blonde heroine in blue gown in a grand ballroom

A Cinderella-inspired fantasy ballroom scene. Foreground: a young blonde woman with a soft, radiant complexion, wearing a pale blue satin ball gown with an off-the-shoulder neckline, fitted beaded bodice, and a voluminous layered skirt; delicate tiara; her hair in an elegant updo; she gazes forward with a dreamy, slightly surprised expression. Background: grand opulent ballroom filled with masked guests in rich period costumes, chandeliers, gold accents, ornate decorations, and colorful banners; warm, golden lighting from chandeliers creates luminous highlights and soft shadows; polished marble floor mirrors the scene. Textures: satin, silk, lace, velvet, crystal; color palette emphasizes icy blue, gold, ivory, blush pink, with jewel-toned accents. Style: highly detailed cinematic fantasy realism with painterly touches, subtle glow, and gentle particle dust for magic. Composition: shallow depth of field, focus on the heroine while the crowd is softly blurred; slightly dynamic camera angle for drama; mood: magical, romantic, fairy-tale atmosphere. Optional: add twinkling sparkles and a soft glow halo around the heroine.
