Melbourne street portraits

I've always enjoyed going for a walk and taking photos of people and things that I find out in the city, I think its a habit my year 12 art teacher passed on to me and its something I've always had fun doing whenever I've had the time. I unconsciously started a series of street portraits about a year ago of people doing there thing on the streets of Melbourne. Most of these subjects I never see again but the guy with the Heineken tram behind him I've seen weekly for the last year, usually around Swanston st and flinders st station because I'm always walking everywhere. It would be interesting to follow him around for a week and make a series of portraits of him.
