Life form study

First post in a few months.. sorry to have been M.I.A. for so long!  It's been a busy summer but now I'm back to school and figured it was about time I share some current sketches.  I was working on this form study for the last couple of days.. after realizing I need some work on life drawing and capturing expression.  The first sketches were done without any reference while I used reference images on the second set.
