In this tutorial, we learn how to color with Copic pens. First, grab a picture that you want to color with your pens. After this, start to color in the picture with your different colored pens. After you fill in the colors, use a darker colored pen to add in shading and make the lines darker along the sides. Continue to color in your picture, adding shading where you prefer. Add in different colors and make the lines darker when you want them to look more bold. Make sure to add in highlights to different parts of the drawing to make it look more realistic as well.
