New pastel self-portrait in progress

I realized today that I haven't really done a self-portrait since I started running a year and a half ago and lost weight. I had some time today after school before teaching my night class at the Art Center, so I started working on this small 8" x 10" pastel.

I started out with a pencil sketch before building up a base layer of color with conte.  I sprayed a light coat of fixative and am letting it sit for the night. Tomorrow I'll finish it with soft pastels.  

I'm pretty happy with it so far.  What do y'all think?
