Tomorrow I'll be joining the long pose life drawing session in Dublin again. For today's study I looked at how Michael Hampton approaches the head. No surprise he uses the same construction and measurements as Loomis.
These studies are from his book which I highly recommend buying if you are serious about drawing the human figure LINK.
I then drew heads based on some poses from my usual reference sites.
And a long pose, focussing on construction and using line to describe form.
