Adding shading and highlights to your chibi drawing can bring it to life! To create shading, imagine where the light source is coming from and darken the areas that would be in shadow. This can be done using a pencil or other shading tool. To create highlights, use a white or light-colored pencil or marker to add small dots or lines to areas that would be hit by direct light. You can also experiment with blending techniques to create smooth transitions between light and shadow.
