In drawing lessons, each student works at her own pace on the drawing of her choice. (Men are allowed too, but this class happens to be completely feminine.)Below:
Jane, on the left, sat outside a house and did a very nice sketch of it. She decided she’d like to do it in the highly accurate and detailed manner that I teach. So, she is working out all the dimensions, learning about perspective, and getting the “bones” of the drawing in place before she gets to the shading stage.
Elainea, on the right, has a very endearing photo of her grandson reaching for a Christmas ornament. We cropped it, and then she did a tracing of the main shapes. Next, she drew the shapes on her good paper, looking only at the tracing instead of the photo with its overwhelming details. After all the shapes were in place accurately, she began shading the child’s face.
In very difficult or demanding subjects, I usually instruct my students to begin with the main part. My theory is that if the main part doesn’t look good, then you don’t have to spend time on the rest of the picture. Also, if you do all the other stuff, then sometimes the fear of wrecking the drawing will cause paralysis.
In other words, “Life’s short – eat dessert first”.
