I never had any formal drawing tuition, and until recently had never done any life drawing.
Then, in 2016 my wife announced that she had booked me into a life drawing session as part of our local village festival. This was held at the local public school and led by Peter Harrop. The session was packed, but I enjoyed it very much - though I wasn't too happy with results. Still, when I found out that Peter led a (fairly) regular Saturday morning session at the school - I signed up.
I am now (2019) in my fourth year. I think there has been improvement?
