Youre interpretation of the form is nice and I appreciate the way that you are using your lines; they are bold and confident, and not sketchy and loose. I think that you would benefit from approaching a figure drawing less from the mindset of "I am drawing a human being with 4 limbs and a head" and more from the mindset of "I am drawing what I see" if that makes sense. It looks as though when you are drawing the figure, you are prioritzing the figure making sense with how you would approach drawing a human being. In figure drawings this quick, it is more beneficial to have looser construction lines, almost scribbles.
