Anime Weekend Atlanta IV - Bruce Lewis on Manga - Oct. 11, 1998

Bruce Lewis draws Western-style art in his job as a commercial illustrator, but he also has studied the manga style of drawing in his previous jobs as artist on the Robotech and Star Blazers comics. Lewis has studied the differences between the way comics and manga are drawn, and he's found  that it goes beyond the superficial. 
Lewis demonstrated the differences at his AWA panel on Sunday. First, a typical American-style comic face: jutting jaw, small eyes, prominent cheekbones and anatomically proportional features. This face could be the prototype for dozens of 20th-century comic book heroes.
Then a manga-style face with large eyes, stylized eyebrows, small, vestigial nose, sloping jaw and tiny mouth. The pattern can be seen in male and female faces drawn in Japan. Both the American and Japanese drawings are recognizable as faces, but the differences are clear. What Lewis noted is that the differences are more than a matter of style - they're the differences between Western and Eastern cultures.
Lewis uses the phrase "abstraction versus depiction" to explain the difference. American comics try for a nearly-literal rendition of characters as they would appear in the real world, he said. Japanese manga tell the stories of their characters in their faces. "The eyes are a symbol of the inner character," said Lewis. "The face is more of an easel - a blank canvas for the expression of emotions." In manga, the smaller eyes typical to American comics are reserved for villians. What Lewis didn't mention, but is obvious through a close examination of faces, is that manga artists have stylized their Asian facial features in their drawings. Yu Watase, for example, looks very much like the characters she draws - from the shape of her head to long legs and arms (Watase is unusually tall).
Now that the manga style is fashionable in part of the comics subculture, some comics artists are trying to incorporate that style into books intended for a mainstream audience. Lewis said he's not impressed with those efforts, because it tends to only graft large eyes on Western bodies and heads. "You have to think in Japanese, almost, to draw a manga comic. Otherwise it'll look stupid," Lewis said. And, while some Americans say that manga and anime characters look alike because of the big eyes, Lewis said American comics characters tend to look the same to manga readers because of the small eyes.
