One of the new art ideas I learned from the figure drawing class I've taken recently is this - a drawing with good shapes results in a good drawing. Conversely, a drawing with bad shapes results in a bad drawing. Even if one can draw anatomy, but without good shape design, the drawing usually ends up a bad drawing.
Here's the breakdown of my drawing process: First, the simple shape of the gesture using a basic construction as the lay-in. Second, using the Reilly method on the head and adding some anatomical marking on the body as a guide. Third, drawing and defining the shadow shapes while being mindful of the anatomy. Then finally, adding in the whites for the lit areas and continue the rendering to the finish.
