Three quick pointed observations:
1. Most obvious the North roof pitch being completely solid would look better if it were broken up in anyway; streaks of windows, a running crease or two coming out from the West peak down to the East.
2. The East entrance apex looks like a lonely portal in a back alley.
3. I did not see every minute of the presentation, but did the give any credence to the plaza whatsoever? They mentioned park like green spaces, at grade approaches and, sky'walks', but for the most part it looks like a slab of concrete.
Initial impression was negative for the aforementioned points, but there are elements I like. The images on the website are growing on me:
