Lots of short poses on Tuesday, here are some sample.
A continous line with left hand then right. About 2 minutes each.
A one minute followed by a "not looking at the paper" 2 minutes.
One minute each with foreshortening. These would be interesting in longer poses.
Drawing with both hands. 3 minutes each - switched between left and right for the charcoal and charcoal pencil.
A couple of 20 minutes drawings to finish. First in an oil based pencil:
Then in charcoal and charcoal pencil:
