Ok, not as loose as I'd imagined, but expressive and not too tight, for me anyway. :-)  The most important thing for me is that due to this wonderful course I drew a person that looks like a reasonable representation of a real man.  I  had no confidence and have not attempted a portrait ever as I could never in any attempts draw a face/person that didn't look cold, flat and not alive.  So, even though it's not as free as I'd like, it's still a major victory.  I will of course keep practicing.  Thank you so much Toby, you're classes are changing my life.  I hope to one day be as free and confident as you are.
