So Fed Ex guys must be slower than the Brown Truck guys? The ones I see here are always moving so fast lol. I admire you being able to get all these street shots of people. I get nervous pointing my camera at strangers :D Beautiful DOF too.
I like the expression of this person and the context that he is in. The people in the background form interesting outlines.
(The pose of the person, is the only thing that I am getting a little stuck on and is leaving me with a slight discomfort as a viewer. I am wondering, maybe you would have approached him from different angle.But in that case you would have lost the background. Or maybe you would have pulled a little back to increase your canvas. ..Just wondering...).
I think you did a perfect job getting the distance from the subject right using the widest aperture setting on the 50mm prime lens. It's not an easy task!!!
