Sketch Based on a Shape

I try to draw every day. Often I base the sketch on a shape. It might be a circle, a square, a triangle, or any other shape. Since it is Valentine's Day, the obvious shape is a heart. So here it is!

"Heart Shapes, February 14, 2016," graphite on paper, approx. 8" x 10"

What makes a good work of art? I think it is often the application of the principles of design as evident in this drawing. Contrast of size, a change in direction, contrast of value, repetition of shape, and a sense of movement are all part of the principles. The basic element of this drawing, the subject matter in this case, is the shape of the heart.
