Sunsetting Skyscraper in the City

Posted this shot in one of the recent competitions and it's rating just above a snapshot. I've always enjoyed this photo, but I also know I'm partial due to my lack of exposure to larger cities.

Taken in Boston as part of a family trip, I like how this building had multiple hard angles and colors to compliment the multiple tones in the sky. I framed the shot in such a fashion as to give some reference, and left a bit of the rail way in to "ground: the shot.

After multiple color grading tries, I selected this radiant warm tone to accentuate the evening sun and orange tones present in the building.

I'm curious to see what thoughts this group has about how this image could have been improved.
