Skull duggering

I got a Wacom tablet not long ago and I've been slowly adapting to it. To get more accustomed to the way it works I have been using photos as reference, and trying to boil them down essentials with the Wacom. 

Heres a skull I did. 

And a wallpaper version in 4D (just like 3d, except it doesn't work) if you're so inclined.

Can make some custom wallpaper sizes if people want em.
