.Masterpiece, best quality,A dreamy Art Nouveau scene in the style of Alphons Mucha, depicting a woman in a flowing, ornate dress with intricate floral patterns. She lies in a peaceful slumber, surrounded by ethereal Halloween elements: a full moon casting a soft glow, pumpkins and autumn leaves scattered around. The composition is centered on her serene face, with the moon above and the Halloween decor framing her. The lighting is soft and magical, enhancing the dreamlike atmosphere.
