Figure 04

Done as part of a practice session with poses of 10 minutes in length. My current goal is: Reduce stiffness and make my drawings feel more dynamic, energetic, fluid Trying out a technique I saw in a tutorial video, drawing a vertical and horizontal line at the start of each drawing to use as a guide.
Retrodictionary
My favourite is the man in the bottom row: He has a really strong line of action but he also seems 'balanced' somehow -- do the guidelines help with that?

I think the stiffest of the bunch are the women on either end of the top row. They're also noticeably more anatomically distorted than any of your other drawings. It might be worth taking a step back and spending some time on how the torso connects to the hips, so that any exaggeration is a deliberate choice to accentuate the line of action and not a source of accidental stiffness.
