Hello hello! Practice looks great! Keep up with these! I only did a few adjustments on parts that were sticking out to me. They were not human mistakes but also very common spots to interpret it wrong. Now that you have a decent grasp of the human figure, it is time to incorporate gesture, or line of action, into posing. In gesture drawing (and figure studies), a line of action is an imagined, frequently curved line traced across a figure to symbolize its primary movement, force, and attitude. Instead of concentrating on details, it serves as a fundamental guideline that enables artists to create dynamic, energetic poses by "hanging" the torso and limbs along this curve. Line of action can be applied to relaxed poses as well. Here we can see it comes from the top where the torso hangs on the arms as legs are the supporting element (plus it makes it a more dynamic silhouette). This line is the core of drawing natural posing and avoiding stiffness. Beside this, the minor mistakes are mostly the perspective matter. Its important to follow each element with extra care due to overlaps. You can also help yourself with a perspective grid for cases like this. Hope it helps! Happy learning! | Artwod Feedback
