A mysterious figure cloaked in a deep, dark hood, their face illuminated by an eerie, dim light. Half of the face is human, with piercing, vivid green eyes that seem to glow, framed by strands of wavy, chestnut hair. The other half is a skeletal visage, with exposed bone and hollow shadows, creating a stark contrast between life and death. The background is a shadowy void with faint hints of blue mist, adding a sense of cold mystery. The overall mood is dark and ominous, evoking the essence of duality between mortality and the unknown, with a focus on the haunting, otherworldly gaze of the figure.
