Modelling a skull in maya

For my 'Do It Yourself' item i chose to model a skull because i wanted to challenge myself. It wasn't that difficult to model but it was hard to get the brow ridge right and i think i could have done the teeth a lot better. To rotate the skull as a whole i first had to parent all the teeth to their respective part of the skull and then parent the jaw bone to the main skull mesh so then everything moves and rotates together and not separately.
