This one is all Adobe Illustrator CS5, using a few gradients. I went about it in a similar way to the Photoshop portraits, in that I didn't use an initial sketch. I generally start with the right eye and build from there. Often, when I render something like this in Illustrator, or logos, especially, I end up getting something that is really close to a finish, and use that as a templet to re-render. The first "final" rendering is for an understanding of form, and the second for refinement. The second one is always much faster.
