So I've been doing these quick 60 seconds gestures. I've probably done almost a couple hundreds of them.

I find that some poses are just hard, like the stiff, standing ones and the lying down poses. You can see how the figure on the top right looks like shit and you can't even tell what she's doing. That's one of those.

I've been looking at different people, and they all do different stuff. For example Vilppu and Proko capture the "flow" with a few strokes put in the right places, while others like Sycra just scribble all over the place "carving out" the form.

What do you guys think? And what do you do? Any advice?
