I learned next to look at the edges of the object that I am drawing. This is also known as contour drawing and it is helpful as it gives me an idea of the overall shape first and then I can fill in the details later.
As per the instructions from Draw from the Right Side of the Brain, I constructed a picture frame from cardboard and a picture plane from transparent plastic with crosshairs drawn with marker. I used this to trace the shape of my hand first, and then removed the picture to fill in the details by looking at my hand directly.
The drawings before show my progress before instruction and after.
