A spectral and sinister version of Shrek stands in a shadowy swamp, his head tilted with glowing, empty eyes resembling those of a soulless creature. His green skin, slick with slime and streaks of blood, glistens eerily. Half obscured by swirling mist and darkness, his expression is a haunting fusion of anguish and malice. The atmosphere around him is chilling, filled with deep blue and dark green tones, exuding a sense of dread amidst the decaying vegetation. The scene, depicted in full figure, is a horror tableau with muted grays weaving through the color palette.
