Emerging from the Page

I came across this drawing while straightening out my flat files. It is a life drawing from the class I teach at DuCret School of Art in Plainfield NJ.
I leave alot of drawings at this stage out of necessity, I usually only sneak in a little work on my own drawing for one sitting (15-20minutes), the rest of the time I work the room and instruct one on one.
I like the drawings at this stage because there is evidence of the process, the drawings tend to be a bit more caligraphic early on and have a feeling of being part of the page in some areas and emerging from it in other areas.
