I love these shots. For me ‘street’ is most challenging not just because the moment is gone in a flash, but it can really push us outside our comfort zone. We may feel it’s rude to point a camera at someone but the chance of getting a ‘keeper’ pushes us to do it.
For me there is a lot of rubbish on the internet that passes for street photography. It’s often little more than random snapshots. Why I like your shots is that they invite the viewer into the seen or they make them think/laugh etc.
I think on the first shot I’d blur the background a little as it is pulling the eye away from the people on the bench.
But who am I to critique, I haven’t posted a shot yet :-(
