Here's a pic of the copper accents mentioned by Klazu, but I don't know if those are to come or have been deleted?
The as-built balcony railings don't look like they are copper, but the 2nd and 3rd floors from the top look to have copper panels
- could be the start of installation all the way down the tower?
EDIT:
Found this rendering and the copper panels are only on the top 3-4 floors, and the copper fins and railings may have been deleted.
