This moment is dragged my attention.. his pose and movement, the right moment and the exact pose of his legs - exactly in the middle of the movement adding an energy to the moment, his visible shadow, the parallel stripes and the feeling of the peeping. All this makes this street moment working perfectly for me.
Personally i prefer wide angle lens for the street and as a grandfather of the street - documentary photography. 28 or 35 are always in my preference, but as i said - it's just me.
