Cold, honest truth here:
You're technically drawing, but in art terms, you're doodling. Nothing wrong with that, but you need to start down the path of actual art education. As amatuer art, it's fine, but it can't be judged by the rules and aesthetics of serious art.
Like someone else posted, /beg, and start downloading and reading the books on the fundamentals of drawing.
If you have the means, you might want to look into a night or weekend beginning drawing course at a local college or community college, as well.
