Thanks to all the people that showed up to the lecture here is the basic ideas that I was trying to tell you guys about.
Things to keep in mind:
-Silhouette is important!
-Look for landmark features and emphasize them (every person will be different)
-Over doing it is better than under doing it
-Don't try to be nice :)
Ways to practice:
-Isolate facial features
-Study the anatomy of the face
-Study the structure of the face and how light affects it
In all honesty the best way to practice is to just go for it. It's fun to do and really hard to stop.
