This says vertical and those two lights at the third level of glass catch my eye.

I like the way the glass mirrors the sky. The clouds also add interest. You may want to crop a little at the bottom so the glass continues to the bottom of the frame.

Nice blues.

i really like this shot. the 2 reflections of light near the bottom are a little distracting, as well as one darker one nearer to the top of the building.

Up! I like the two lit windows.

Very striking.

We've seen so many of these shots of buildings in the first day or so of this theme that I'm starting to rate them lower. Not that this is a bad shot, I just don't think you're covering any different ground than the other buildings already here. Also, the two lights in the lower windows really jump out and steal focus.
