Sketches - People and Hockney

From a previous post, you can see how Hockney, with a few lines and gestures, can create a compelling sketch of another person. I had tried to do something similar with the 25 Second Sketches. I was a little bored one day during sketching class. Maybe "bored" isn't the right word; distracted may be better. I was distracted one day and thinking about the Hockney sketches that I had been looking at. I was a little envious of the ease by which he seems to be able to sketch people. As a result, I thought maybe, instead of just trying it with buildings, I should see what I could do with people. Below are 3 sketches of people who were around me (and unaware that I was sketching them).
