Your sence of form and proportion is really good. What Id suggest is to start off with doing some hand a foot studies, once youve done a few of thoes move onto full body and start by just drawing the shapes you see; start with a line of action, it can help you focus on the flow and where the weight for the body is placed. Then move onto shapes, the head is a oval, the upper torso is a rounded box, the pelvis and hips are a rounded v ect. But overall your off to an amazing start!
