Really interesting shot. It leaves a lot to the viewers' imaginations. The guy on the left has an expression that is almost intimidating, although admittedly it would be hard to feel that a guy who's wearing a singlet bearing a kitteah in a bow tie is a dangerous street-punk. The girl wears an expression that seems to sit somewhere between wary and intrigued, while the guy at the back seems to be simultaneously part of the group, and yet separate from it. You're really getting street shooting down to an art with shots like this.
