I've decided that I want to really learn how to draw. Drawing clothes on premade doll bases is all well and good but it doesn't leave much room for flexibility. I'd like to be able to draw my own poses, shapes, faces, etc. I took some art classes about 10 years ago. >.>;; I did pretty well at it then but I didn't keep up with it. And I never learned how to draw proper anatomy. Like this kind of thing I guess?

So does anyone have any advice or good resources for me to learn? By the way I'm interested in realistic drawing, not anime style. And I can't really afford to take classes.
