Step 2 Now choose the Scratchboard tool, which acts like a real-world inking brush and can achieve really nice thin lines and heavier lines too. When you start to ink on the layer above the finished line-work, use the pencils layer beneath as a guide. Use thin lines for face and hair and thicker lines for clothes and shadows.

Step 3 To ink all the straight lines, you can use the straight-line stroke mode (V) and the Thick n Thin brush variant. Create straight lines that are thin for forms that are in the distance and use thicker lines for forms that are closer to the viewer. The more detail you start to put into the environments at this stage, the more believable and interesting your finished page will look.
