Hi, Mark. I think you are onto something with the muscle memory. Your strokes look great! I am doing every exercise at least twice, once on paper and once on the iPad. I have done a few exercises more than once if I felt I needed it, or just enjoyed it. I am looking forward to seeing your next drawing.
MarkI think you did well. I have done this one many times.I find if you turn the paper sideways, it seems easier to draw a better reflection. I call this one the EKG monitor (or lie detector) sheet.alohamea
