Did some life drawing exercises from a book I bought off Amazon a while ago. If you're interested, it's 'Atlas of Foreshortening: The Human Figure in Deep Perspective' by John Cody & Ron Tribell. It contains heaps of poses, both male and female. It's still better to draw with a real model in front of ya but just bit of exercises whenever you feel like practising at home.

These were done in charcoal and white conte.
