Welcome to the pile PariahJack. We are all very nice here. Most of us aren't even legally obliged to avoid children.
First thing you can do is consider the forms of the body and the perspective from which we are looking at it. If you get the shapes and angle right it will automatically improve the life of your artwork. A good way to practice this is to pick a reference photo and trace the shapes in it, what shapes it is made of, what is the angle. Think of it as a 3D object (I usually try to do this by guessing first and then tracing to better understand the things that looked bad in my initial sketch).
If you feel like you are not making any progress, make a list. What things do you need to improve in. Focus your studies. Examine the issue thoroughly. Ask why you are bad at that particular task.
