I think the setbacks need a bit of work. Multiple setbacks can create a nice visual rhythm and progression like on 30 rock. But the setbacks on the south tower particularly the second pair of setbacks don't seem to accomplish that. From the render it doesn't seem that they distinguish themselves enough from the central portion of the tower or align themselves well between the first setback and the roof. It reads more like the shoulders of 311 S. wacker than the nicely aligned steps of 30 rock.
