Waiting at the bus stop

My current photographic exercise is monochrome street shot.  So as I was waiting for a bus home, I thought I'd try a few and this is my favourite.
I'm enjoying the mono part of the exercise and will keep it going for a wee while.  Not too sure about the street scene though - still feels a bit sneaky.  However, there are some strong expressions coming through.  I'll persevere.
