For details like the outlines of the eyes, the nose, and the mouth, I’ve actually treated them as shapes to be traced and then later filled, instead of trying to create solid tapering lines. Creating variable-width lines in Flash with a single vector path can be a pain in the rump, and this way is easier and gives me more control over my line weight. They can always be colored in with a solid black fill later, to create the illusion of a solid black line.
Just a note: as a rule of thumb, I always put the actual eyeball part of the retraced eyes on a layer separate from the others, and always retrace them as full circles/ellipses instead of just the lines that aren’t obscured by the lashes/eyelids. If I want to animate moving eyes later, I won’t be able to do it properly if all that I have available to tween is a truncated chunk of eyeball without the upper or lower curves.
