To be fair, it seems to blend into the sky because of its glass. I find it annoying that a such a large new tower is that dull when I see it, but I think that those who don't know anything about it will barely notice it's even there.
If we want to have components of the city blend in with the sky, then we should just go with the sky: it's far cheaper.
If we want to create a city out of buildings however, why not stand out from the sky a bit?
