In those tutorials i explain in depth how to proceed when making a hand, head or body. Either sculpting or drawing. This videos will help you understand better the common mistakes and how to avoid them.
Those videos are also in Youtube for free :). I have spent many hours practicing for those videos to make them most useful, so if you want to aknowledge my work, you could buy them.
The hand video camera capture of my face is a little desynch with the sound, but this doesn't bother with the clip itself.
