Some form drawing study

This is more form than anatomy.  This is an older drawing.  People have been asking about anatomy. 
Anatomy is useful to know if you know how to use them.  I was studying how shapes and forms
slightly vary when the muscles are in use in this drawing.  I use anatomy more to close off forms, push flow, show action, etc..
I don't just draw it in because I see it or because I know it's there( drawing out of my head )
