There is a lot of line confidence improvement overall I would say. But your latest ones are too detailed for Gestures.
You are putting in outer contour landmarks for hands and feet and calves and forearms and boobs and armpits, all stuff like that which distracts from the overall goal.
Focus more on how the energy flows through the figure which creates abstract rhythm lines from the head all the way to the feet. Or at least from one side of the torso mass to the other, one side of the leg to the other.
There are many opinions and ways to do this. Many posts will even say "gesture" but are fully formed figures drawings and not abstract representations of motion in any way.
Here is a talk I did about gesture not too long ago. Give the response a read and see what it is you are trying to specifically manipulate.
Here is an example to show what I am talking about.
Now this might be a lot to absorb but lets break it down.
The Left one is pure gesture lines I never lift my pen there is no form and this takes seconds.
The Right one is pure Rhythm abstraction where I focus on one side of the form, making an action line, and then the second line I'm making for the other side a 'character line' defining the width and depth of the body parts mass.
The middle one is just a sort of hybrid that some people do. It's still capturing the gesture and correct proportions of the pose.
Now you can look up the force method as well which I touch on in that other critique but it is basically the rhythm abstraction but with much more curvy line confidence which also pays more attention to the anatomy as you build in instead of pure abstraction.
But what it boils down to is this. The proportions, width and height relationships, and the motion of the rhythms through the figure.
Hope that helps! Keep posting.
