Okay, so this is how I sometimes do it. If you looked at the tuts, you'll notice that everyone starts a little differently. Some like to start with the eyes, others with the nose, some with the mouth. I start with whatever looks like it'll be the most fun to start with and work from there. You'll notice in the image that I started by placing a single polygon in the scene and positioned it to math the drawing I have by changing it's angle and shape slightly. Mind you now: I don't always start with the lips...sometimes I start with the flesh surrounding the lips and then extrude the lips out from that. This time though, I didn't. No real reason.
