A timelapsed screengrab of the whole sculpting process of my third personal head study.
The session was recorded at 5 frames per second and played back at 30 so it's sped up about 6 times. The overall sculpting time came in at about 2 hours, but it wasn't all recorded in a single session. I paused it periodically to save, study the reference and so on. It was sculpted over about 3 evenings.
Head sculpted in Mudbox2011. Base mesh made in Silo2.
