Create a highly detailed, cinematic portrait of an anthropomorphic alligator dressed in 18th century pirate attire, complete with a neck tie. The alligator character should embody the qualities of a video game character and be rendered with realistic, cinematic lighting. The portrait should have a dramatic and dark color palette, akin to a high-definition, 4K portrayal found in an HBO series. The character’s expression and posture should suggest a sense of cunning and adventure, with subtle creative elements introduced to enhance uniqueness while maintaining the core pirate theme.
