Create a highly detailed and professional artwork of an ethereal angel with flowing hair, holding a large lotus flower. The angel has delicate, intricate wings and is dressed in an elaborate, ornate gown with swirling patterns. The color palette is soft, featuring pastel blues, greens, and pinks. The background is a dreamy, abstract blend of colors, giving a sense of serenity and otherworldliness. The style should be a unique blend of fantasy and realism, with a touch of Art Nouveau elegance and a painterly finish.
