First, congratz for getting through your first months of drawing! I know how painfull it can be, to learn drawing from scratch and i really hope that you keep will keep going!
From what i can see, your focus seemes to be getting the overall figure down, you draw circles to show the volumes of the head, ribcage and pelvis and describe the directions of the extremitys. I think this is good so far. To be honest, a year ago i used to draw exactly like you do and thats a perfectly fine way to start with. From here on i think its important to make clear what you want to say with your drawings and when you finde out what that is, you can start working on the expression and the"language". With expression i mean the gesture of your figures, consider working in more expressive mediums like chalk/charcoal/pastel/ink and start to really "go at it" these will also help you to loosen up. Back then i started using charcoal and drawing with it was really fun, your hands get super dirty and the drawings need fixation but its worth it. With "language" i mean the way to convey your expressions, like anatomy, perspective, lighting, shape language, but also gestural lines and so on. The thing with that stuff is, its really like a language, if you know a few words and use them in a smart way, you will be able to say a lot.
In that regard i think it would help you a lot, if you can show that the figure really stands. Draw them feet and even better would be, to show that there is weight, gravity works on everyone. Another thing that will have tremendous impact on your drawings is, if instead of the spheres you would draw cubes for the ribcage and pelvis. Unlike spheres, cubes show dimension, they have a distinct front, back, up-and down side to them. But be be aware, those cubic forms will make the figure look very unorganic and stiff if there is no gesture in them.
