Street photography; Flinders Station & people

The following photograph, I thought had the right mix of elements to make it stand out. The main objective in capturing this image was to represent Flinders Station. The idea was to get up close to it, and picking out features unique to it that would describe the location of the picture; Flinders station. While composing to include the times of all the different train platform departures as well as portions of the station’s sign, the time of the photograph itself was also deliberate.
Deliberate to capture the two characters on the lower left corner of the photograph, involved in an act of public display of affection. I guess I hadn’t thought of this, but capturing the station all on its own seemed rather dull. It was the life and people around it that gave character to the place. During this instance there was a large gathering of people, supposedly from the “punk culture”. Unfortunately, there had to be this other figure, on the lower right corner, rushing to escape from my photograph that doesn’t seem do add much to the picture, and if anything detracts from it. Right now I’m thinking, recomposing the shot so the couple were in the middle bottom of the picture would actually improved the picture.Above all, The image isn't that clean cut, and I think people might struggle to notice what the photographer was trying to say with this picture...
