Burg Schädel Gothic Architektur Prompt

Picture a massive, ancient skull with empty, hollow eye sockets forming the main structure of the castle. The castle's entrance could be through the open jaw, creating an ominous gateway. Incorporate architectural elements like towers and spires emerging from the skull's surface, adorned with gothic details. Use shading to bring out the textures of bone, and consider adding subtle cracks and weathered features to give it a sense of history. Maybe there's a soft, ghostly glow emanating from within, hinting at the secrets hidden inside.
