We went to MoMA this afternoon. I didn't have great luck. I tried quite a few sketches at MoMA and on our way there, but, unfortunately, many of them I was unable to complete. People were very mobile and they left before I could finish their sketches. Here is one which I got only the outline. A couple sat in the outdoor space of the MoMA to take a rest.
On our way to MoMA, I grabbed the following sketch on the subway. Toward the end of the drawing, the subject realized what I was doing and wanted to see it. And I also took a picture of him.
