Scott's eyes in that image resemble those of Link from The Legend of Zelda: The Wind Waker. In most drawings of him they are rounder.

Oddly enough -- in 2001 some test footage from Wind Waker was released, showing a Link with some very almond-shaped eyes. The appearance of Link was retooled so they look less almond-shaped and more mukokuseki.

The cover of the first volume isn’t really all that representative, that’s right. Here is a page from the fourth volume: http://www.scottpilgrim.com/images/previews/v4pre/v4pre__027...
