I think the biggest mistake people seem to make in trying to create teen female characters is failure to observe the real thing. Teenage girls do not generally look like Anime characters, but this seems to be how most people's attempts to make teens turn out. For true realism, try working from an actual photo of a real teenage girl something like what you're trying to recreate. Take measurements of the face, the relationships and distances between features, etc. If your modeling software allows it, you could even import photos to use as guides when you are making the morph targets. -Adam
