This drawing of a hand is another “picture plane” exercise from Drawing on the Right Side of the Brain. (That is not an affiliate link. This post is about one of the lessons on that DVD.) Basically, you place your hand under the acrylic window and then trace the projection with a dry erase marker. Once done, you now have an outline of 2D representation of your hand on the clear window. This is much easier to draw since it is flat. You then draw this object on your pad and add in the details.
This is one of the earlier exercises and the first one that I felt that I had really drawn something well. Shading is one of the last lessons, so it is not that good at this point. Still, it is good enough that this looks like a real hand.
