Create a portrait of a fantasy water elemental doll with ethereal aquatic features. Her skin is a translucent blue, like the shallow waters of a tropical sea, with a subtle glow from within. She has two large, oceanic blue eyes that are clear and deep, reflecting the vastness of the sea. Her ears are delicate and fin-like, contributing to her water elemental nature. Her hair is a flowing cascade of various shades of dark color, giving the impression of water falling in a serene stream. Her expression is peaceful and enigmatic, with a hint of the mysterious depth of the ocean. She is adorned with a crown made of Sapphire, diamond and pearls, and her blue attire is a gown that resembles water in motion, crafted from fabric that shimmers like sunlight dancing on the water's surface.
