Cheers THX, a Zombie's a perfect one, I'm surprised that no ones done it to be honest!

Blocked out a head and a torso so far.going to keep blocking the rams and legs and pose him/it then adjut the base. Just need to get a flow going.

Though it going straight in to Zspheres for the base but, well I'm old and like the Maya base mesh -> Zbrush workflow, I can then determine the overall topology off the bat (granted it would be easier to go straight in and sculpt!
