: Lines that follow the "wrap" of an object's surface to show its 3D form.

Instead of drawing outlines, start by sketching the three-dimensional "skeletons" of your objects. Most complex pieces are just combinations of:

Use different strokes to add texture and depth to your piece:

Shading gives your objects weight and volume. Follow the to create a realistic 3D effect: Highlight : The spot where the light hits directly. Halftone : The true color/value of the object. Core Shadow : The darkest part of the object itself.

: Light bouncing back from the surface onto the shadow side. Cast Shadow : The shadow the object throws onto the ground. 3. Practice Sketching Techniques

: Good for rough textures or organic environments.
