Looking up

Drawing from photos of people looking up. I used the same circle template that I used in class earlier this week. I am completely ignoring the cheeks and just looking through to the shape of the jaw since I think I'm confusing the two. A projection study of just the jaw will be next. 

I've mentioned before, I've been slowly making my way through Harold Speed's The Practice and Science of Drawing and the latest edition of Drawing on the Right Side of the Brain by Betty Edwards. The bottom drawing is what I was thinking about when I was trying to work out the difficult angles above
