How the 'feeling-out-volume' technique and descriptive line drawings made us feel?

When I first tried this technique I found myself over thinking it and became frustrated by the outcome.
However, once I became accustomed to the “swirling” or ‘volume creating’, my line drawings started to create a dimension I could have never have created without the interior. I think the trick was to just let go and to literally feel the forms we were drawing.
A great new trick! 

Thank you!
