In today's two 15 minute and 1 30 minute sessions I went over some sculpting in Zbrush tips by working on my original character Smooth's big brother.
-- using insert sphere/cylinder primitives together with using clip brush and move to make eyeLids/lips/ear
-- using planar brush to recreate ear by removing old ear
-- using flatten brush to create planes on face
-- using smooth on qremeshed mesh to improve mesh shape
-- reusing a starting head shape to practice new zbrush techniques
-- using anatomy reference to roughly figure out proportions if started with a free style sculpt of mesh
-- using draw over to help refine sculpt
still need to work on
--topology in Maya that maintains style of drawing and preliminary Zbrush sculpt.
--face rig in Maya
Hope this was helpful.
