highly realistic diorama showcasing a natural stone arch over a fast-moving river. The arch is constructed from rugged, weathered rocks with patches of moss and grass growing in the crevices, adding to the lifelike texture and age. Below the arch, whitewater rapids rush over rounded stones, with clear resin used to convincingly simulate the dynamic flow of water. The river appears turbulent and energetic, cascading toward the front of the diorama and spilling slightly over the wooden base edge, enhancing the illusion of motion.
