I'll give it another shot =s. When you sketch on paper how large do you go?
For stance study of non-realist characters, a 3.5" notepad is usually enough. Something as simple as a round head, triangular (or cross-shaped) chest and some legs can already provide help. Last time I tried seriously it turned into this and that.
I usually just use a normal sheet of paper, or some larger than average drawing paper. I sketch small sketches until I've pretty much filled the page, and if I'm still not happy by then I move on to a new sheet.
