O'Donnell's sketchbook

@Ursula - Thanks a bunch for the tip on the back of the skull!! I tried to keep that in mind especially with the studies I did today! The polychromos piece took about 15 hours I think :) Thanks again :)

@ShinOkami - Thanks very much! Yeah really like his book and diagrams are awesome. Steaming ahead trying to learn as much as I can :)

Some more head studies today from Michael Hampton's book.
