I was kind of hoping that the 20 story gap was lower, say closer to Wacker Dr, like in the original proposal. That way pedestrians/cars/buses passing by can look down into the grand LSE neighborhood.
If somebody else already made this critique then I apologize--I was too lazy to read the last 3 pages
