Hi there!. I would suggest using lines of varying thickness and darkness and contrast this with light and soft lines!. If you are working in pencil, do this in the softest pencil lead you can!. I would also not use straight lines because you need to be using your pencil to describe its soft moist and fuzzy looking appearance!.Www@QuestionHome@Com
