Mulher anjo em estilo art nouveau em um salão celestial

A melancholic yet hopeful Art Nouveau female angel with dark brown hair and glowing honey-colored eyes, stands in a grand ballroom under a starry dark blue sky, wearing a golden Venetian mask and a flowing Art Nouveau style dress made of sunflowers and silk, surrounded by yellow roses and surreal dreamlike elements, her dark brown feathered wings spread wide as she gazes upwards in a celestial atmosphere, her expression a balance of sorrow and longing, as if caught between the beauty of the world and the pain of its impermanence.
