What are some techniques for creating smooth pencil shading in comic art?

For smooth shading, use blending techniques. You can use a blending stump (tortillon) to soften lines and create gradients. Alternatively, you can use your finger (though be mindful of smudging!). Feathering lines, where the pencil strokes gradually fade into one another, also contributes to smooth transitions. Light, even pressure is crucial for achieving a smooth finish.
