And to answer Andi's question, no, it wasn't the composition I was going for, but to be fair, I was just seeing what I could get. The camera was on a low step - I wanted to get the light on the manhole cover (which I did get in the frame, yay!) and the pedestrians going by.
It took me a few seconds to make out the walker in the foreground and think it really adds to the 'feet' in this shot. Now, tell me, was that the composition you were after? it works either way btw.
