ZBrush time lapse head sculpt by flint read 

No sound but, I hope my sculpting helps you with ideas/inspiration
The sculpt was done over 3 hours with a 128 definition adaptive geometry ball, and ended up at an adaptive level of 512.
I used mostly the move tool clay build up and dam standard brush, in combination with mask and move / mask transpose techniques
Please feel free to comment and or criticize (constructively please) my work.
I will also try to answer questions if I can :D
