That's a lot of concrete on the southern facade. I know that the River Street tower will block much of it, but there will still be some poking out above. I wish they'd clad it with the black paneling used on the other facades.
The western face surprises me most -- half of the top portion is covered in metal panelling. You'd think the western side would have the best views of the river and downtown. This tower is clearly oriented towards the east and north, which makes sense give its close neighbors, but is definitely different from most of the other buildings here, which put a premium on western and southern views.
