Tapered Glass Crown: Softening the Taper and Top Illumination

Design a supertall office tower in the manner of Cesar Pelli as a tapering square shaft with softly rounded corners, its curtain wall of white metal fins narrowing gradually until the top storeys dissolve into an open perforated crown. Compose the tower rising far above a dense city, the crown's transparency letting sky show through the structure, vertical fins catching sunlight down the whole shaft, low neighbouring roofs for scale, clear cool morning light, low view up the shaft, 24mm lens, architectural photography, ultra photorealistic, 8K
