Long and detailed tutorial on sculpting techniques

[Maenas]

I came across a wonderfully described and documented tutorial. This was provided by a sculpting yahoo group that I've been a part of for awhile. This guy shows how to sculpt and paint a sci-fi bust from scratch. Went on to win Gold at Euromilitaire. This is a a very long tutorial, so requires the Drop Box app (free) to read. But you won't regret it...

Two or three posts later on that thread, Maxxx, commented and shared two interesting pdf on this same topic.
