Awesome work, SOB . . . great work with the vectors, and the idea of you as different characters is so simple, and so original . . . that it makes me KICK MYSELF FOR NOT THINKING OF IT FIRST!!!!!
Really, great stuff. I have one small peice of criticism regarding your girlfriend's pics . . . it's the jawline . . . I dabble in Illustrator a bit myself, and can see the seam between the jawline and the chin. Again, this is a small piece of criticism, but it would really improve the quality of the pieces, especially if you plan on keeping them going.
Another thing that would be interesting to see would be an actual pic of you and your girlfriend so that people can see what kind of features were embelished, etc. . . . to get an idea for how the characiture has evolved from an actual person.
Great stuff, though . . . truly
