Let me share with you, there is not a single artist here that has not struggled with gesture drawing. I have been practicing for years and it does seem like an uphill climb; however, there have been tools that have helped me grasp the concept better. As you can see from the initial paint over, I stressed the direction of flow in the underlying form. The arrows are to illustrate that there is a balance of flow and rhythm throughout the entire body when you know to look for it. In the legs down to the feet. Same is found in the arms. I attempted to provide other examples where a minimal amount of lines were used, yet you can still see what the pose is supposed to be. In the ballet jump, I tried to only use three main curves to get from the thighs to the feet. For me the gesture is the most important aspect in what my character is doing. By the way, I was not sure what your pose was trying to convey; however, it inspired my imagination toward playing basketball in a defensive position. I pray that this will be helpful on your artistic journey and keep practicing. You will get it.

Hey there! I understand the frustration; a long time ago, I went through the same thing, feeling like my drawing wasn't improving no matter how much I practiced. I'll recommend what worked for me, hoping it helps you too. :) What I did was, instead of focusing on drawing complete figures, I focused on certain parts of the body and gradually expanded from there. For example, I can see that you have a hard time simplifying the torso. Focus on improving just the simplification of the torso. Learn how to simplify it using simple shapes like a bean, and then gradually add complexity. You can keep the limbs simpler to avoid distractions. Personally, focusing on learning how to simplify the torso was what helped me improve my gesture drawing. :) Of course, I still struggle with it a bit, but my drawing feels more fluid. :) Look at the work of other artists such as Michael Hampton, Diego Lucia (Diluc on Instagram), artists from Force Drawing, etc., and imitate their drawing techniques. Draw in the same way they do repeatedly. Gradually add more complexity as you become more confident. :) But start with small sections. I made the drawing slightly more complex, but you can see the simple construction I did with the blue lines. :) Hope this helps!
