Women's Mouth/Eyes - I'm fairly good at drawing lips, but I can mess 'em up pretty easy too. I love how they do the eyes--I've tried to get mine to turn out that well, but. This is a pretty sweet look at the different angles.
If your having trouble drawing a person, think about the shape of the eye first. This way you get a realistic look to who it might become! O my goeh this is the most helpful thing ever with anime eyes :D
