I couldn't help but notice the similarity this building has with one of the skyscrapers in my city:
Elysian:
Mid-Continent Tower: (The one on the right)
However, the difference is that one of these is much older, and it isn't the one Chicago. I don't have a problem with these kind of buildings in skylines, in fact, I can't imagine not having the Mid-Continent Tower in my skyline. But it annoys me when we live in 2006 and people still propose buildings that would have been at home in 1956. They were great back in the day, but it's really time to move on.
On the plus side, it's got great height, but I can't help but feel that it's a wasted opportunity to have built something as modern and striking as the Trump tower is, if not nearly as tall. That's just my opinion anyway... Apparantly, people with millions of $$$ don't mind.
