I think the podium is actually quite good. It's open and inviting with enough variation to make it interesting. That being said, the colour choices and materials do make it feel very disconnected from the tower. The two don't appear to flow well together.
As much as I like to pile on Cidex, and as much as I dislike the east west exposures of the tower portion...after seeing the podium in person up close on the weekend, it isn't bad. I'm fine with it, the materials actually look decent, the grey spandrel portions aren't that prominent. If it were in a location that faced the river, etc..I would say that it wouldn't be up to par but it is fine for where it is. I actually quite like the way the rust portion with the black protruding boxes turned out.
Walked by this one today and the 'top hat' public art has been fully installed. I have to say I actually quite like it as a public art piece. It resembles the shape shown in the renderings but it's completely covered in graffiti with the top hat worked in multiple times. Now that it's complete I have to say I really like the street presence of this one. Just don't look up above the podium.
