แม่มดแห่งความมืดในพิธีกรรมลึกลับ

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, her silhouette stark against an intense glowing magic circle. She has [dark curly hair in a loose messy bun with long tendrils framing her face] and wears a [black] floor-length gown with an open back, a thigh-high slit, and torn shadow-like ribbons or vine-like wisps trailing from the fabric around her body. Behind her stands one enormous circular arcane sigil made of concentric rings, geometric linework, occult symbols, and three pentagram medallions at the top, left, and right. The setting is a gothic stone hall with tall shadowy pillars, drifting smoke, and a glossy reflective floor engraved with a partial summoning circle in the foreground. Lighting and color: A stark two-tone palette of [neon emerald green] and black, featuring extreme contrast, dramatic backlighting, volumetric fog, and crisp rim light. Style: Detailed dark fantasy illustration, symmetrical composition centered on the glowing sigil, ethereal supernatural atmosphere.
