The next thing I did was take tracing paper and trace the photograph onto tracing paper and then enlarge and photocopy that image onto white paper to be painted by my daughter. If your child is older or has interest/desire, you could let them do the tracing. You may have to darken the lines they would be copying with a marker or something to better define it for them to trace. My daughter wanted me to do it so it would be "perfect" - haha!
Lastly, we of course, signed her artwork rendition after we mounted it to a piece of construction paper and we affixed the original Master she was emulating next to it. She really enjoyed this activity. We may do it with each artist!
I felt this exercise was a good one for studying the Masters in fine art. It certainly helped her to notice the details and understand better the artist's intention in conveying a story through his art.
