How I can improve my poses

I always had problems with poses and gesture. I don't think I'm particularly bad on anatomy, but my poses always look pretty stiff and without life. Also it's pretty difficult to me to make new poses from imagination. So I enter in this page to try to practice poses every day and try to be better at drawing poses and gesture, and I would want any critique and or advice to be better at it. I'm struggling with the clases. 

Here are the drawings I made yesterday in the 30 minutes class, they're divided by the amount of time I drawed every pose:

hi Eli
uhm, generally i think the way to improve that poses from imagination muscle is to actually, create a pose from imagination (i struggle with this, but i do try)

also on your photos, i think your low times are getting good flow and gesture, while your longer times have good proportions to them. maybe you're losing some of the life of the gesture as you start giving yourself more time to get it down ?

Maybe is bc I focus too much in having perfect anatomy 

Next time i'll try having more life and flow in what I draw instead of centering on anatomy

You're definitely on the right track by practicing consistently. Even without seeing every drawing in detail, gesture drawing is something that improves with repetition, and 30-minute sessions are a great habit to build. One thing that helped me was focusing less on anatomy at first and more on the overall flow and line of action. Once the pose feels dynamic, the anatomy becomes much easier to place. Keep at it—you'll probably be surprised by how much progress you make after a few weeks of daily practice.
