its a pretty decent tutorial, however it does not cover a lot of what you see. For example it covers the construction of the base body mesh, and sculpting but does not cover the creation of the clothes just the sculpting of them, and a lot of the parts are just imported from maya like the knee pads etc so you never get to…
I don't know if you could expect everyone to have bought the dvd. The images in the tutorial and on his personal website look pretty amazing though. Base your decision on that, or try asking around on their forums.
