Thunder Shrine Maiden Portrait

Create a dramatic vertical fantasy portrait of {argument name="character name" default="Oyagi"}, a powerful Japanese thunder shrine maiden suspended in a storm. She is shown from mid-thigh upward in a dynamic floating pose, body angled slightly to the right, head tilted back with a calm fierce expression, long black hair whipping in the wind, one arm extended downward-left with elegant fingers and the other lowered at her side. She wears layered white translucent kimono sleeves with delicate floral embroidery, a dark navy skirt, a white fitted bodice, ornate red waist cords and tassels, silver chains and charms, and dangling earrings with red accents. Behind her is a circular sacred halo frame holding exactly five large silver tomoe drum-like emblems: one at the top center, one upper left, one upper right, one mid-left, and one mid-right. The entire scene is monochrome deep cobalt blue with bright electric white highlights and small red accents. A jagged lightning bolt enters from the upper left, crosses in front of her extended sleeve and torso, then branches down toward the lower right, illuminating rain droplets, mist, and fabric. The background is a turbulent night thunderstorm with dark clouds, rain, water droplets on the lens, and layered silhouettes of Japanese maple leaves and flowers around the edges, especially large pale leaves at the lower left and upper right. Use cinematic photorealistic fantasy art mixed with Japanese mythological illustration, high contrast, ethereal glow, intricate costume detail, flowing translucent fabric, storm energy, sharp focus on the face, painterly blue grading, no extra characters, no modern objects. Add a small elegant signature and date in the bottom-right corner reading {argument name="date text" default="July 22, 2026"} and {argument name="signature text" default="Oyagi"}.
