Practice is good, for lack of a witty phrase

Class was canceled this week, but I was able to supplement my drawing education by attending both open drawing sessions this week.  I have mixed feelings about my drawings as of late.  Im happy about how much I am able to tackle in a short amount of time, yet I am struggling with proportions all of the sudden.  I feel I have fallen a step backward and my drawings are starting to get away from me.  Im hoping that some instruction in class could straighten this out.  Here are three longish poses from the last several sessions.  I seem to have success with the legs but the chests need to become more dimensional.
