Well I posed this 質問 because I was doing project for art and in the end i decided to do a pair of dancing ballerinas and the shading is probably what made it turn out as good as it did so thanks for the アドバイス everybody.
Despite my lack of experience with charcoal, I find that shading works very well when working with charcoal. The charcoal flows very well across the paper as あなた are doing the shading.
