Anime Girl

Anime characters may employ a variety of predetermined facial expressions to denote moods and thoughts. These techniques are often different in form than their counterparts in western animation, and they include a fixed iconography that's used as shorthand for certain emotions and moods.
There are a number of other stylistic elements that are common to conventional anime as well but more often used in comedies. Characters that are shocked or surprised will perform a "face fault", in which they display an extremely exaggerated expression. Angry characters may exhibit a "vein" or "stress mark" effect, where lines representing bulging veins will appear on their forehead. Angry women will sometimes summon a mallet from nowhere and strike another character with it, mainly for the sake of slapstick comedy. Male characters will develop a bloody nose around their female love interests (typically to indicate arousal, which is a play on an old wives' tale). Embarrassed or stressed characters either produce a massive sweat-drop (which has become one of the most widely recognized motifs of conventional anime) or produce a visibly red blush or set of parallel (sometimes squiggly) lines beneath the eyes, especially as a manifestation of repressed romantic feelings. Characters who want to childishly taunt someone may pull an akanbe face (by pulling an eyelid down with a finger to expose the red underside). Characters may also have large "X" eyes to show a knockout, or in some cases, even illness. This is typically used for comedic purposes. Vacant, non-reflecting eyes can be used to indicate a state of semi-consciousness.
• Animation technique
Like all animation, the production processes of storyboarding, voice acting, character design, cel production and so on still apply. With improvements in computer technology, computer animation increased the efficiency of the whole production process.
