Very slow, subtle camera orbit of only 3 degrees over the entire clip, at a constant speed, distance and height. The entire diorama remains static. The central stacked sculpture is rigid: its total height, block dimensions, proportions and positions stay exactly the same from the first frame to the last. All buildings and landscape retain their original shapes. No growing, rising, stretching, scaling, block separation, independent rotation, morphing, wobbling or zoom. Keep the entire scene centered and fully visible, with unchanged lighting.
