Spectacular job on how you render your gestures and forms of your poses, but if your goal next is to make your drawings the least stiffest and the most dynamic, then the lines of flow could use the most work, so why not knock yourself out with 1 hour of 1 minute poses of figure poses? As a result, like I mentioned before, your lines of action and acting will become the least hardest and the most free-est and liveliest and motivated internally. For most info, please look at the gesture drawing for animation videos online on YouTube and in ebooks. Good luck!
