Quite good! You should find some paper without lines to draw on though.
You're definitely not a hopeless case, and you seem to have a decent grasp of anatomy and proportioning already. What I would suggest is to either get a few books on drawing comic book/fantasy figures (which seem to be what you like to draw), or at least look around the web for some tutorials. They'll teach you to draw from the inside out (at the moment you're drawing from the outside in), where you first lay down a "skeleton" of your figure which allows you to get the pose, proportions, foreshortening, etc. in place before you start adding the details.
Learning to draw "comic book" characters is also good for studying anatomy, because not only do you learn where all the visible muscles are and how they move, but you learn how to exaggerate them as well - in both directions - to create characters that fall outside "realistic" anatomy (take Gollum and Hulk as two examples from either ends of the spectrum). A good book will also teach you foreshortening techniques for making pictures with a lot of impact (i.e. make them look badass).
Good luck!
