OK, I have to agree with most everyone on this - you're crazy.

Everyone is so used to seeing a horizontal skyline - a proven formula. It will give you a good stock shot if you need it sometime (didn't you post a pano shot a while back?). Vertical looks great here because of the reflections. Maybe a print would show the reflections better, and they probably go down closer to the bottom of the frame. Plus it also leaves space for text if it was going to be used as a stock image.

Hmm... that sky does look familiar for some reason.
