(2.19.19) 10-min figure sketches

This looks great, the proportions look good and the pose does not appear too stiff, I notice that the leg closer to us seems to bend a little in the thigh area which seems to be should be drawn straighter, otherwise a good 10 minutes drawing

It looks like you've done a fairly decent job of capturing the technical pose of the figure. I can see what you mean by stiffness; fluidity is definitely something that comes with practice. My suggestion, is that when starting a pose you not focus on it as what ever it is. First express the pose with fluid gesture lines, then expand on that with basic shape, and lastly, only after the aforementioned steps, add detail.

I am in no way a master but these are things that have helped me. I've spent more time doing the 30 and 60 second gestures just to learn how to loosen up and not be so precious with my initial lines.
