Nice shot, cozzyd.
I'm really excited for this tower still, but I'm starting to think that it's not really going to stand out that much. Yes, the materials and form are different than most of the boxes that make up the downtown skyline. But this is really only going to be slightly taller than surrounding buildings, so it won't jump out from all over. Moreover, it's slender (which is a good thing), so it won't really "dominate" the view as some of the other older structures do (I'm thinking 1 Beacon, 100 Federal, 1 Boston Place and 1 Financial).
The plateau aspect of the skyline is one reason people consider it somewhat unremarkable. I also think the incredible girth of some of the most notable buildings (inc. the ones I listed above) adds to the stumpy effect of the skyline. I do think Boston's towers look shorter than they really are from a distance.
The MT won't do much to change that or add much scale. It's going to succeed most at filling a gaping hole in DTX and adding both more retail and pedestrian activity to the district.
