Addressing weaknesses

My brother-in-law Matt likes to say to "address your weaknesses". So while at the zoo I made a first attempt to draw some people. There was a grandfather and his grandson sitting in front of me and since they were being relatively still I took a shot at drawing them. Fortunately I couldn't see their faces, so it made it less intimidating. I don't really like this drawing, but I figure it is a first step in getting better at people drawing.
