How do I effectively use shading and highlights in anime comics to add depth?

Shading and highlights are essential for creating a three-dimensional appearance in anime art. Start with a light base color, then gradually add darker shades to areas in shadow. Highlights are added to areas where light would naturally reflect, such as the top of the head or cheekbones. Use soft gradients for smooth transitions and sharp edges for more defined shadows. Consider the light source when applying shading and highlights to ensure a consistent look.
