I am feeling rather ineffective, there are so many excellent, precise drawings up here and miine are all scruffy and very inprecise. I have always thought that if you want a very precise drawing, use a camera and I do that for other artwork. this is not a criticism of those who wish to draw or paint in a photo-realistic manner, it's just that I get very down knowing that I can't do it.
