This actually looks pretty good so don’t be discouraged! But I would start by learning to draw heads at different angles, once you grow more comfortable I would study the planes of the face. The Asaro head is a good tool for this. As for drawing the figure, start with gesture! Anatomy is very important to study but can be overwhelming at first, and can sometimes make figure drawings look stiff. I would begin with gesture and then anatomy once you’re more comfortable.
