I think one of the glaring problems is I've noted with a number of renderings of these proposed buildings are depicting themselves in the glow of twilight hour...where the colours reflected back make it look much warmer, appealing and more organic then they end up ever really being. As it's true, when light is reflected of the building's respective window wall at that time of day will mostly convey that. But it's really deceptive, because we know the building once it's completed, doesn't look like that for the most of the daylight hours. Leaving a pallet of greys, devoid of any real warmth and life...
The devs do this because they likely know grey here is cheap. But probably unpopular, unless they can obscure that fact in a rendering without displaying it at night. The warm glow of an after sunset (or before sunrise) time frame gives the building far more welcoming appeal that it's ever justified. Yet, it does the trick. /le sigh
