after you have finished and you have some poke throughs, those are easily corrected usuing the morphing brushes.  There are three good ones, push, pull and smooth

Push and pull require a magnitude strength of about .o4 and the smoothing brush around 1 and try the smoothing brush first.  If you bork something up do a cntrl z (that is the famous undo function for a lot of 2 and 3D software products).

When you are through there will be a dial generated for your morph.

Just save your work BEFORE applying the morphs.

The morph brushes are located under Editing tools third row, third column (Pose room)
