This image shows the opposite of a glassy skyline. The only true glass building, which reflects sky and water, is the one just above the boat. The rest of the buildings are more traditional sky scrapers with mixed cladding.
Maybe. But I can count something like 6 or 7 buildings on that pic which look glassy to me.
I'd say there are several glassy (which reflect sky and water) buildings there [1][2].
