The truth is, though, some truly fantastic portraits have been created in Illustrator and other vector art programs. And the process can be as difficult or straight-forward as you choose to make it. Most designers seem to start out with a photo, though others have been created from scratch and may even be fictional characters with no reference image. In any case, the end results are fantastic, whether they’re kept a bit more abstract and two-dimensional or they’ve gone for a more realistic final result.
