Having seen the initial, non public design before what was released to the public as the "initial design", this revision is a welcome addition as there's an inherent improvement and emphasis on the materiality and overall quality albeit at the expense of the massing and original concept.
This looks to be a typical tower on podium design and the central public plaza seems to be completely enclosed with units above in the podium; the previous designs had multiple interior terraces and skylights above the plaza.
The non public design basically had a similar massing but the towers were a dense extrusion of oblique pixelated tubes with curved glazing on each of the tube. Each facade of the tower probably had around ten of these tubes so you can only imagine the cost of it. Detailing was similar with terrazzo and bronze. The podium was basically your typical Heatherwick waffle structure but followed the same density of the oblique grid of the tower above, similar to their Toranomon-Azabudai project in Tokyo except at a much higher density.
The green terracotta cladding on this iteration will most probably be similar to The Fitzroy in New York designed by Roman and Williams and developed by JDS. I'd assume a similar tone of green if not lighter. Here's some close up shots of the terracotta used on the Fitzroy:

111 West 57th Street by SHoP and JDS is also another example of how terracotta cladding can look nowadays. There's deliberate modulation in the panels to create a moiré effect from afar.
In either case, I'd assume the terracotta to be glossy in these contemporary examples rather than matte like in older towers such as the Woolworth Building
