Create a hand-drawn illustration of Iemanjá, the goddess of the sea, depicted as a middle-aged woman with Afro-descendant features. Her skin is dark, reflecting her deep connection to the ocean. From the waist down, her body transforms into the tail of a mermaid, with shimmering scales. The scene should be dominated by shades of blue, with no other colors, evoking a tranquil and mystical atmosphere of the deep sea. Iemanjá is holding a berimbau, a traditional instrument, in her hands, symbolizing her power and wisdom. Her face is adorned with a royal crown, softly glowing, symbolizing her dominion over the seas. The crown is made of marine elements such as shells and corals, reflecting her celestial nature and her connection to the ocean. Additionally, her neck and wrists are adorned with pearls and jewelry made of sea materials, highlighting the richness of her underwater kingdom. Although she wears minimal clothing, her figure is subtly covered by a cloth that shields her breasts, while her eyes are always veiled with an ethereal, transparent covering, adding an aura of mystery and spirituality. Iemanjá's pose conveys serenity and power, as if she is in a deep meditation or invoking the waves. The illustration should have a hand-drawn, sketch-like quality, with intricate linework and soft shading, capturing the peaceful and majestic essence of Iemanjá, while maintaining an aura of divinity and reverence.
