Rob, I guess I would suggest you check out some of the well known Street Photographers and their styles. Many conduct Workshops in various locations. Once you find some you like check out their sites for info.
A few years back, Eric Kim was conducting a three day workshop in Mumbai (easy for me to get to) but I could not make the dates due to commitments. He is a bit modern for me but I do like his work. I'm pretty much self taught with a bit of training in PJ.
For many years I shot 'Stand Off' , more documentary, but over the last couple of years I've started using shorter focal lengths but not really 'in your face'. Many more wider angle lenses also.
You might want to check out Nikon USA. I know Nikon UK periodically have Street Workshops. I get emails from Grays of Westminster offering workshops in London conducted by well known Photographers but alas, none have ever matched up with my trips to the UK.
You might also look for local DC Street Photography. You may find an interesting group or photographer locally. I know of one active group in Calcutta but that is the other side of India
Best of luck,
Tom
