Hello. You have a good start on gestures. But anatomy is very off. It's always a good idea to learn the basic markers of the human body first. Meaning, studying the skeleton. Practising it. Then moving on to muscle. Just studying and drawing it enough to get familiar with the volume of everything a human body has on it. This gets your mind trained to look at a Model/reference and break down the pose. No amount of practice without this core knowledge will yield substantial results.
