I'll chip in some positivity and say that I really like how the color of the glass turned out on this one. It's this nice dark blue with a tinge of green that has a high quality look to it. Given that this tower is basically a glass rectangle it's a good thing they didn't go with something like the glass on 6XG, which cleaning issues aside I don't think looks particularly nice.
Good point, and agreed. I like the glass on this one. Kinda reminds me of Spring during certain parts of the day.
Not that I'm against it, but I think when this is completely finished it will most definitively fall under the "evil buildings" category of architecture.
