Getting that Chin Right

Still not really practicing the eyes, ears, nose and mouth but added a little bit more detail to try and figure out how things should work. The absolute hardest part for me right now is getting the chin and how low it should go right. I know there's a difference between the male, female, and children chins/jaws so I was going for female this time around. I did a couple before this and the jaw/chin was way too wide so i couldn't get the point just right. I think the part I kept forgetting is you only use a nearly perfect circle when your character is looking straight forward otherwise the width of the head is too much. This one came out a bit better by making a slight oval instead.
