A spectral and sinister version of Shrek stands in a murky swamp, his head tilted, eyes glowing vacantly like those of a soulless creature. His green skin is slick with slime and smeared with traces of blood. Half-hidden by the swirling mist and shadows, his expression is a haunting blend of anguish and malice. The chilling atmosphere is painted in hues of deep blue and dark green, creating a disturbing scene amidst decaying vegetation. His full figure looms in the eerie setting, enveloped in a horror-filled gray palette.
