A spectral and sinister Shrek stands in a shadowy swamp, his head bowed with glowing, vacant eyes like those of a soulless creature. His green skin is slick with slime and streaks of dried blood. Half-shrouded by mist and darkness, his expression reveals a haunting blend of anguish and fury. The atmosphere is chilling, suffused with deep blues and dark greens, unsettling, with decaying vegetation all around. A full-body scene of horror, tinged with gray tones.
