Hi Sarosna! Good to see you again. :)
I really like the gestures you drew and posted. I can tell that you get a little hung up on details every now and then, so it's really good that you managed to focus more on the gesture! Quite a few of them have great motion, so keep up the good work! :)
There's no one 'right way' for this, but it helps to break the bodies down further. Don't mind the contours of the body so much and try to focus on the break-down of the different parts.
Start with the spine line, trying to make it a fluid line (c-shaped at most, never s-shaped). Draw a circle for the head, draw a circle/oval for the rib cage, then a circle for the hips. With these three shapes down, you can add the joints at the shoulders and hip bones. From there one you can break the legs down into joints and limbs. If you skip the joints in the legs, you risk drawing legs that aren't anatomically correct.
I've never drawn animal gestures before (my personal focus is humans), but I drew this 30 second gesture just now to illustrate that the basics are still the same:

Does this help you?
