Hi! Although I'm not a master at figure drawing, I hope I can help! I think these are a great start. Finding the line of motion is a wonderful way to start learning how to draw figures. From what I notice, your gestures are somewhat stiff so I think it'd be beneficial to exaggerate it a bit more to express the motion of the pose. I think the center line could be pushed more to be less straight to help with that.
With short gestures that are a minute long, the goal is to create lines that capture and imply movement, rather than copying the pose's exact proportions and angles. I recommend pushing the curves and lines created by the motion of the body rather than the outlines. It'd be good to practice finding the stretch and compression of a figure.
excuse my gestures, but hopefully, this gives some visual insight into what I mean.

I think the resources below will do a much better job of helping demonstrate and explain!
This first one really helped me when I started doing gesture drawing as I didn't know what to focus on when drawing figures in such a short amount of time.
This channel specifically focuses on figure drawing and he has great informative videos about gesture drawing!
Overall, I hope that these are helpful!! And I'd love to see more of your work in the future!
