Let me pass on to you the best advice I've heard when watching streams and talking to other artist about figure drawing.

Keep your poses loose. By this they mean people don't just stand straight up unless they try. Look at some photo references, they shift their hips to the side, tilt the rib cage, and twist their torso and back. You have fairly straight spines, but keep it up! I mean you are off to a good start, but there is always room to improve.

Do like I'm doing and sketch manikins in different poses and from varying perspectives. When you draw them they won't be perfect, just try to see why you don't like it and improve that on the next one.
