In a shadowy swamp stands an eerie and menacing version of Shrek, his head tilted forward with glowing, hollow eyes resembling those of a soulless creature. His green skin is slick with slime and streaks of crimson, partially shrouded by the thick mist and darkness. His expression is a haunting mix of anguish and fury. The atmosphere is chilling, bathed in deep blues and murky greens, unsettling, with decaying vegetation surrounding him. It's a full-body horror scene infused with gloomy grays.
