Sketchbook Vine Charcoal Graphite Drawing#6 - Young Woman

Hi everyone, I've been hanging out in the Portraiture forum at WetCanvas  the last couple days, and came across one of their Challenges, this sketch is a result from one of their references. I just couldn't resist those eyes, they just drew me in.
Sorry, it's not a great photo, will get a better one, and still not finished with this study as yet, but wanted to post it, and see where it needs some work.
I've got some more poses of her I'm going to do.
This took about 45 min, quick go at her in my Sketchbook used mostly graphite and some Vine charcoal so far, about 9x12inches. I'm quite pleased with her. I just love that look in her eyes!!!!
