A selection of observations:
Those staircases are incredible. I can't wait to go up and down them next time I visit. I've never seen a city with so many public staircases.
I actually really like the base. The building's massing is very Lever House.
Those balconies could be a big suicide magnet. Rich, but unhappy people who climb over the railing of their balcony to the open ledge, and jump...and splat. I'd probably climb over out of sheer curiosity and/or daring, if I had the chance.
