Spontaneous Portrait Three

Been doing a little project for my A-Level Exam..

I'm basically researching Street Photography and the overall theme of 'Structures' - If you haven't guessed already, I'm looking at the variety and differences in people's faces, as well as fashion.

~ Just to clarify; I don't know ANY of these people! ~

It was scary just going up to random people and asking for their permission to take photos of them -- but they were ALL really nice! Only one person declined?? :]

Thanks for looking!!
