If I get on dA, I'll be sure to let you all know.

I've never given art advice before, because no one has ever asked for it. I'll try to give you some pointers, but I don't explain things very good.

Well, the way I do it is I try to imagine where a light source is hitting on my sketch and then I just go from there. Also, I go from darkest to lightest, so if a light source is going to hit the left side of the drawing, I work my way to it by starting on the right side and making that part really dark and gradually getting lighter. Also, I use my fingers to smudge up the areas that looke too jagged, so it looks smoother when you're transitioning between the values of the shades.

It took me a while to get the hang of it, but after all the practice I had, it finally clicked with me. When I first started out, I would practice shading simple shapes, like circles and stuff. Eventually I worked my way up to more complex shapes and finally got to where I could shade the human figure pretty decent.
