Undressing female nude back side charcoal sketch on paper

Vine charcoal heightened with a charcoal pencil, middle values handled with a blending stick, also known as a tortillion. The most important thing in drawing is understanding the structure, then seeing abstract shapes properly, that usually comes from direct observation, the eyes need the proper training, eventually they start 'seeing'.
