A couple of five minute sketches

 Just trying to warm up, donchaknow.

Gestures...

 ...and a quick plaster bust study.

Lines and smudges

 The long pose.  I really enjoyed this one and loved the shapes and edges.  Took some time and did only a partial figure.  However, very satisfying.

Just a cast shadow

 Just a little doodle... er, serious study.

Why... so... serious?!

 It may have something to do with having to hold this pose for 15 minutes.

Take a seat...

 

...and take a load off.

10 gestures in 10 minutes
