壮麗な舞踏会の大広間に立つ青いドレスの若いブロンドのヒロイン

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.
