I thought about the distance between the two and how it compares to other places so I looked at Chicago. Sears to John Hancock 2.4km, 1 Bloor West to Skytower 3.1km...
Glass looks good but the white panels were a wrong choice they do not contrast properly with the color of the glass.
Yes it looks fat but remember 300m....so it's going to look almost like a pencil tower from the north/south views.
