Hey Max, When we say gesture drawing, what we are talking about is the flow of the pose. We want to find a long flowing line to describe the pose. The lines we use should be either a "s" curve or "c" curve. The reason this is so important is that as we add structure and details, it can stiffen up the pose. As you can see in the drawing, you used straight lines to describe the pose which causes it to be stiff. I hope this helps in your gesture drawings going forward :)

I think what you could do is focus less on getting proportions + perspective right and more on capturing the feel and motion of the pose. The perspective and proportion on these look good, but the top one looks kind of stiff. For gesture, it's helpful to start with drawing something like a stick figure. A way you can start doing that is draw one line of action that captures the main movement in the pose, it usually follows the movement of the spine. You can also add lines for the arms and legs. You won't draw a lot of lines, and usually the lines you draw will be pretty big. The way most people practice gesture is by doing a bunch of really fast drawings, and usually when you start out they'll be pretty messy. Practicing gesture is also a great time to get used to using an overhand grip.
