Both sides now
Continuing the series of quick drawing techniques that I have encountered at art classes in the past, today I present upside down drawing.
Again, these are from the ASOC Summer Art Experience in 2013. Here are four drawings on two sheets of paper.
For each sheet the drawing of the model is first done upside down and the next drawing is of the model in the same pose but drawn right side up. I can't recall how long was allowed for each drawing but it would have been no more than a couple of minutes each.
