I actually like KPF's CTF Guangzhou design the best (although the ICC is gorgeous). The setbacks, vertical striping and the slant of the roof are all nods to iconic New York architecture. And it's massive, but you wouldn't know it to look at the renders because the proportions are so good -- tall enough to feel elegant, bulky enough to feel substantial.

Although I'd love to see a spire on this tower, something like the CTF Guangzhou would be a perfect fit, for my money. Or maybe a less-busy version of the Tianjin Rose Rock IFC.
