Design an elegant ballroom in the palace, with rich decorations and refined details, such as luxurious curtains, chandeliers and tapestries. The setting should reflect the grandeur and sophistication of the place. Show the exact moment of the transformation. Place the frog in the center of the scene, with a magical glow or light effect around it. The transformation process can be represented with sparks or a glowing aura, showing the metamorphosis in progress. After the transformation, portray the frog as a beautiful maiden in a dazzling ball gown. The maiden should have a serene and confident expression, highlighting her new form and beauty. Place the guests around her, with expressions of surprise and admiration. Show them with open mouths and wide eyes, some perhaps applauding or making gestures of astonishment. The expressions should clearly convey the positive impression that the transformation has made. Add details that emphasize the transformation and its impact, such as a faint aura of magic around the maiden and perhaps a dramatic reaction from an important character, such as the tsar or prince. Use soft, radiant lighting that highlights the beauty of the maiden and the magic of the transformation. Warm, bright colors can be used to highlight the scene and create contrast with the surrounding environment.
