Rituel de la Sorcière Noire Émeraude

A dark fantasy full-body portrait of a mysterious sorceress standing barefoot in the center of an ancient ritual chamber, shown in side profile with her head slightly bowed and her body mostly in silhouette against an intense glowing emerald magic circle. She has {argument name="hair style" default="dark curly hair in a loose messy bun with long tendrils framing her face"} and wears a {argument name="dress color" default="black"} floor-length gown with a very low open back, a thigh-high slit, and long torn shadow-like ribbons or vine-like wisps trailing from the dress and wrapping around her body. Behind her is 1 enormous circular arcane sigil composed of many concentric rings, geometric lines, occult symbols, rune-like markings, and 3 prominent pentagram medallions positioned at the top, left, and right. The environment is a gothic stone hall with tall shadowy pillars, drifting green smoke, faint magical haze, and a glossy reflective floor engraved with 1 additional partial summoning circle in the foreground. Use a monochrome palette of {argument name="glow color" default="neon emerald green"} and black, with extreme contrast, dramatic backlighting, volumetric fog, cinematic rim light, intricate magical linework, ethereal smoke, and a haunting supernatural atmosphere. Make the figure elegant, dangerous, and otherworldly, with ultra-detailed fantasy illustration rendering, symmetrical composition centered on the glowing sigil, vertical aspect ratio, and a mood of forbidden ritual magic.
