Dude, I have absolutely no idea what you are talking about.
Tell me more.
you'd be surprised the difference paper makes first of, if you look at different sketchpads in an art store you can see different types of paper for different effect. I tend to sketch with a lot of shades and darks, because I'm putting that much graphite onto a piece of paper, i actually use paper meant for pastels beause it holds my work better, whereas the smooth whiter paper tends to rub off and smudge. playing around with paper types until you find your style can make a big difference in how your work comes out.
And of course if you get a set of art pencils they come in different weights. There is a whole scale of pencil hardness and softness and the hardness opr softness of the pencil defines what you can do with a line. most schools use the no.2 because its middle of the range, but basically, H's get harder and harder, and produce a fine light line, whereas the higher you get on the "B scale, the softer heavier and blacker your line gets.
If you get a range of pencils you can experiment with the diferent line weights, Dark and heavy is good for energetic action pitures, whereas the finer, lighter lines that come from a pencil on the "H" scale are better for meticulous detail and drafting. you look like you are more of a B type person but if yous tart varying your line weight you'll be amazed at the effects you can generate. a friend of mine sketched a bunch of paper clips once and he got the line weight and shading down so perfectly it was a tromp de l'oeils, the kind of picture that fools the eye and you think the object is really there.
