In-Progress Self-Portrait

The class:  Variable Topics in Drawing/Collage
The professor:  Barbara Campbell-Thomas
The project:  make a self-portrait exhaustively investigating the potential of line, mark, and value.  Employ collage heavily as you "construct" your portrait - constructing being a means of conveying an idiosyncratic version of yourself, not merely an adept visual equivalent.  Ponder how collage's propensity toward fragmentation and juxtaposition might be useful to you in creating a self-portrait.
The photo of my in-progress self-portrait:

The analysis:  I enjoy the tactility of the portrait, the feeling of glued paper - stiff, wrinkly, crinkly.  The ripped edges of the paper lend to its messiness, as does the visible brustrokes produced by the glue mixed with charcoal.  I also love the size (it's obviously not to scale in the photo; it's size is roughly 4' x 5').  My tendency is to work very small and tediously.  I feel with the size of this piece and the nature of its creation I have been able to loosen up a bit.  It's nice to do something out of my comfort zone.  With that, as always, comes trouble too.
I have a little trouble with scale at this size.  Plus, I've never done a self-portrait so placement of my facial features is not coming easily to me.  However, thanks to the nature of the project, I can literally cover my mistakes and rework what I don't like.  I don't like my nose or mouth.  I really need to rework that area.  I use the terms nose and mouth generally because I don't actually have a defined nose and mouth.
Last class I began adding "curly hair."  At the moment, I'm a little unsure about it.  I may add a little more and gradually cover it up until some is poking through here and there so that it's not such an obvious feature.
Definitely still a work in progress.
