Papercraft pop up city with harbor monster and trains

Intricate 3D papercut pop-up book art depicting a sprawling, multi-layered nocturnal cityscape built directly into the pages of an open book. The scene features a dense urban landscape with towering gothic-style buildings, arched bridges, and winding streets, all constructed from layered, textured paper. A large, friendly orange monster stands prominently on a pier next to a blue steam locomotive and a classic white ship docked in a small harbor. The composition is vertical and deep, creating a sense of miniature scale. Lighting is warm and magical, emanating from glowing windows and street lamps, contrasting with the deep navy and teal tones of the night sky and water. The color palette consists of rich blues, warm ambers, terracotta, and deep greens. The art style is highly detailed papercraft, showing visible edges, shadows, and paper textures, creating a whimsical, storytelling atmosphere with a sense of depth and physical craftsmanship.
