Another interesting technique I use is to look at the picture in a mirror. It mostly helps me see asymmetries that I couldn't see before. It's really funny, because I could look straight on at a picture and think it's fine. Then I could look at its inverted image in a mirror, and see glaring problems. I could then look at the picture again normally, and not see the problems.
Perception is a strange thing .
The two sisters decided that they should try to draw Li Mei Lin as well. We looked through the pictures I had on my laptop, and once we found a reference picture everyone could agree on, the laptop was placed between the two sisters, and they started to draw. Linda drew her picture very calmly, but Jinah was a little nervous. She kept looking over to monitor her sister's progress, and she'd make a snide comment every once in a while. You always copy what I do.
