Hi Andrew.
Dont dispare, street is incredibly difficult! Try going to a festival, somewhere where people will be expecting photographers and drinking alcohol, their inhibitions are lessened and youll have an easier time of it, Also try large cities, i took some good stuff in New york and found it much easier because it seemed less confrontational.
Look at what other street togs are shooting and learn from it. A lot of street togs process to black and white, try that, Look for interesting subjects with contrasting light or people with skin thats been "lived in"
Have a look at this, it my attempt at shooting a festival. It was actually quite good fun!
