I like the original as well
particularly the symmetry of it
If anything, a closer equal crop on all sides would also work.
Looking at it again, I might be tempted to rotate it 180 deg so that the hightlights (bottom RH corner of image, also those in the reflections + open windows at the lower RH corner of the centre portion) would be in the top half of the frame, rather than the bottom half of the frame, thus they would draw the eye up thru' the pic to the top of the frame more easily.
