Ethereal East Asian Portrait with Butterfly

Prompt

An elegant portrait captures an {argument name="ethnicity" default="East Asian"} woman looking upward with a gentle, serene smile. Her profile faces the left, and she wears an {argument name="dress style" default="off-the-shoulder white satin dress"} and a single pearl earring. Her dark hair is loosely tied back, and her nails are painted pearlescent white. Her right hand is raised, and delicately perched on her index finger is a large, black and white patterned butterfly with intricate veined wings. The background is a {argument name="background color" default="deep, velvety midnight-blue"}, filled with soft, floating white particles and a subtle sparkle, giving the entire scene an ethereal, magical, and dreamlike quality.
