Create a vertically elongated, rectangular gothic artwork for the back of a t-shirt, featuring Nyx, the goddess of the night, a raven, and a crescent moon as separate elements. Nyx stands at the bottom, her figure tall and abstract, draped in flowing dark robes. Above her, in the middle of the composition, is a simplified, stylized raven with outstretched wings. At the top, a crescent moon is positioned, completing the vertical layout. Surrounding the entire design is a bold, minimalist gothic frame with ornate, sharp edges and pointed details, inspired by cathedral architecture. The design should be black and white, with thick lines and minimal detailing, creating a striking yet simple gothic aesthetic, perfect for a t-shirt.
