Hi, Geirskogul! The images are clear enough. So do poses of those gesture drawing. It's great! I can read all of them.
I think you can improve your drawing with adding line for clavicle bone to emphasize shoulder joint movement. And I see you always stop your line on elbow/knee joint. We don't always need to do that. Sometimes it's better continue line with some curve to feel flow and rythm on our hand.
