A spectral and sinister-looking Shrek stands in a dark swamp, his head tilted with glowing, soulless eyes that pierce the gloom. His green skin is slick with slime and streaked with smudges of blood. Half shrouded in fog and shadows, his form exudes an aura of anguish and hatred. The atmosphere is chilling, bathed in eerie blues and deep greens, creating a sense of unease. Surrounding him, decaying vegetation adds to the horror. His full figure is visible amidst the murkiness, with shades of grey enhancing the menacing scene.
