The exterior detailing and bracing is what makes this tower extraordinary... unique! It will be one of the "BEST" worldwide once built... an instant supertall landmark ... similar to what IM Pei's Bank of China building did for Hong Kong
What's remarkable is... Foster's tower 2 will be another right next store... then you have Calatrava's station... another... it's like the WOW factor multiplied exponentially by 3!
