It's good... what's with the apparently blank white wall on the right, though? "Textured" concrete? Probably the parking garage...
They've definitely changed that part. I really liked the original parking structure as it left the elliptical form intact at ground level for much of the tower. It looks like the updated base looks very similar so it may even be for the better.
One major improvement is the extra "floor" at the crown... while it won't be as striking as the 2 "floors" on 111 S Wacker, I really like this detail as it gives the tower a proper crown w/o breaking the vertical pattern.
