Advanced Portraits -- Painting 3

This is the third painting from our advanced portrait painting class. This was a quick one, obviously, since it is not complete. We only spent one class period on it, with maybe 2.5 hours painting. I'm not sure that I will do any more on it, since I only really like painting from a live model. As a result, it will likely stay unfinished. In fact, I kind of consider it a study, rather than a finished painting. I can see a lot of things I'd fix if I had more time.
