Some observational drawing from our CMT lecture. Anna Notaro AND Chris Byrne (that his name?) were talking today so I got to draw BOTH OF THEM! Thought they came out quite nice, I was quite happy with my sketches. Also got the back of Dave's head as he sat rapt a few pews ahead of me. The picture of the other man is of a gent from way back when who wrote a book about something relevant to the lecture. His face was on the screen for a while so I took a quick sketch. Is that cheating when it comes to obs drawing? I hope not. Anyway, enjoy.
