Design a gothic artwork with a slightly elongated rectangular shape for the back of a t-shirt. The composition features Nyx, the goddess of the night, the raven, and a crescent moon as separate elements. Nyx stands at the bottom, depicted in an abstract and minimalist style, her flowing robes creating subtle curves. Above her, the raven is centered, its wings closed for a more compact look, while the crescent moon is placed near the top. The entire composition is framed by a bold gothic border with intricate, sharp details, inspired by cathedral windows and arches. The design is in black and white, with thick lines and minimal ornamentation, giving it a clean yet powerful gothic aesthetic, perfect for a t-shirt.
