A spectral and sinister Shrek stands in a murky swamp, his head tilted, eyes glowing with an empty, soulless gaze. His green skin is slick with slime and streaked with traces of crimson. Half-shrouded in mist and shadow, his expression combines anguish and malevolence. The atmosphere is chilling, with muted blues and dark greens, a disturbing setting of decaying vegetation. A full-body view steeped in terror, tinged with shades of gray.
