Both videos are so inspiring. It is great to see a real master at work with no limitations. Your workflow is orgainc and smooth - perfect. After seeing this and Planet of the Apes last evening, I am filled with enthusiasm. What tools and settings are you using in the "alien head" video? In particular, how are you making the sharp edges, "crease" cuts and masking off areas of the sculpt for more detailing? Thanks for sharing!!!
