A stunningly detailed, photo-realistic 4k portrait captures a woman embodying the mystique of the Venetian carnival. She wears an intricately designed fox mask adorned with gold embellishments and delicate patterns that catch the light, casting subtle shadows on her flawless skin. Her long, wavy blond hair cascades down her shoulders in a cascade of soft curls, catching glimmers of ambient light. The texture of the oil painting adds depth and richness, highlighting every detail of the mask and the soft fabric of her elegant attire, set against a blurred background that hints at the grandeur of a Venetian ballroom.
