A spectral and sinister-looking Shrek stands in a shadowy swamp, his head bowed with glowing, hollow eyes resembling those of a soulless creature. His green skin is slick with slime and traces of blood, partially obscured by mist and darkness. His expression is a haunting blend of anguish and malice. The atmosphere is chilling, colored in unsettling shades of blue and deep green, surrounded by decaying vegetation. The scene conveys an eerie sense of dread, with his full form barely discernible, enveloped in a palette of murky grays.
