Usually im all about composition, but this doesnt bother me so much...the absolute subject is in the middle and she stands out against the background. Even the other lady blends in into the backgound and basically she rides that train more often thsn you guys do I presume...in that sense she IS part of the background
That is a very cool way to look at it, not so much for background lady :)
Im sure she had her time to shine riding this train already :p
