The observation deck is going to look great, love everything about it! Since the shape of the tower isn't a plain box there's going to be a lot of crazy views of the city! Can't wait to visit when it's finished!
The base cladding, on the other hand, still doesn't impress me. The patterned look looks silly, much the same way on 7WTC. I can't believe that's the best they could come up with.
