First, I'm amazed at the faces you can make without the aid of Photoshop. Second, I'm even more amazed at how much detail you get into these things! I can't do a simple clone without spending way too much time trying to get it right. Do you have "convert teeth to pointy objects" actions and such preloaded?
I was just showing my mom around some of my favorite SPs tonight, and several of yours were in there. This is just another example of why I love poking around your portfolio. :)
