It's great that you're learning a more realistic look, Vanilla! Strange as it may be, a good and realistic human face can be one of the most difficult things to draw. There is a number of reasons for this; one of them being that most people know what a human's face realistically look like and can readily pick up on minor details on the face, so a few mistakes can become very glaring.



Unfortunately, I do not have any specific advice I can offer you since I'm still learning to draw more realistic human myself. =/
