Inking the Drawing
Draw the lines, using the draft as a guide. First, draw the outline of the character and the outlines of each part.

Because you created the "Line drawing" layer on top of the "Draft" layer, the blue lines of the draft are covered by the black inked lines.

You can add variance for decorative lines such as wrinkles in the character's clothing by drawing with a lighter pen pressure to create finer lines.
