Ultra high resolution masterpiece: a visually stunning, full-body portrait of a stylized harlequin holding a scythe, surrounded by an eerie Halloween atmosphere. A woman in a bold red and black outfit, mask, and hooded cloak crouches beside him on a ledge, her checkered patterned attire gleaming in the moonlit darkness. The giant moon hangs low in the background, casting an otherworldly glow. In 4K detail, this badass monster is rendered with realistic, detailed textures, exuding a sense of euphoric sci-fi mystique.
