Mark - I was so surprised to find the station empty in the middle of the afternoon that I didn't really think too much about composition BUT I do agree with your comment. An unconventional angle can bring much more
Very nice! The perfect perspective lines and angles are great. The tiles, rails, ceiling lines, platform lines all work together very nicely. The signage adds some interest to. A suggestion might be to shoot this lower to the ground for more of an alternate perspective... Sometimes shots from "standard adult height" above the ground can be a little too familiar to most of us to grab attention. Nevertheless, nice work!
