Good job Georgia. Keep at it. Practice is the key. Also, a few books like Drawing on the Right Side, there are lots on anatomy recommended here. There are lots of free youtube videos that help too. Just google away, it's amazing what you find online these days.
My suggestion would be to work on proportion and seeing body parts as blocks to begin. If we simplify the body into simple shape rather than getting caught up in detail it can lead to a more dynamic outcome. You will find just a suggestion of a body part can be more affective than trying to draw it all.
