Character prototype for new story

When I start a new illustrated story, I usually make sketches to set the style, especially the character's face.  For some time I have wanted to incorporate a Poser character in order to maintain the facial proportions and have a more consistently recognizable character.  Even though my character in 'A Book of Complaints' is generally the same person, her look tends to change with my whim, and my habit of constantly changing the way I draw the same objects and characters.  Using a Poser character as an armature ensures the proportions are the same, so that my character's nose doesn't become to large, or her eye doesn't end up near her ear, which almost always happens when I draw freehand.  This is really just an excuse to use Poser for something, and it will be interesting to see if I can restrain myself.

The other experiment is with a new tool, using a tapered brush (a G or Maru type) instead of my usual solid marker lines.   The fourth face is done with the brush, and reminds me of the time I used to sketch with a Sumi brush and ink.
