What’s wrong with this picture?

The center line is out of place.

• By highlighting the front line and weakening the lines in the background, we make the volume in the drawing more pronounced.
• Volume is the representation of mass in an artwork or a sculpture. The three-dimensional form of an object or shape is said to have volume. Artists simulate volume in their paintings to give them a three-dimensional effect. This is usually done by applying tones or shades of light and dark areas.
• Volumetric drawing is an essential figure drawing skill that brings a dramatic sense of 3-Dimensionality to drawings. It does this by emphasizing the fundamental volumes of the figure. This technique has been relied upon for centuries and is still used by master artists and creative professionals today.
