Hi!
Your gestures are already pretty good, and have a lot of movement to them! congrats for that :)
As for advice, i have two things: maybe try a bigger pencil, or another looser drawing technique. This could add depth to your lines, and help you step away from drawing similar body types. it seems like you already have a pretty clear artstyle, and automatically go back to drawing similar body types. And seconly, looking at it, it seems like you're spending a lot of time on the heads, where for this type of shorter pose a simple circle does the trick. It'll give you more time to work on the rest of the body. :)
Keep up the good work !
