An obligatory portfolio skull

Every 3D portfolio should have one. Not because we want to see any but because of the process you need to go through to create one from scratch is a great test and worthy to include it. From using referencing to creating the base in Maya to sculpting in ZBrush, then back again into Maya to remodel and UV-map correctly and neatly. Then try to make a low poly version with bump map/normal maps.
It's not perfect but based on the reference I had it was pretty close.
