Second year - Skull Challenge

I wanted to add skull in the layout so I've started off with sketching the ideas so that I could use it as a reference. I've decided to not model the jaw bone to show that the skull has been there for many years.

So, the images below are my attempt of modelling a skull on Maya. It was actually not as hard as I thought it would be, but the most hardest part is to get the right 'dint' at the side of the head and also the shape of eye-holes.
It will be added onto the layout.
