In the March 2009 The Artist's Magazine I found a blog by Terry Miller. He was featured in an article where he discussed his graphite work. His blog Pencil Shavings, pencilshaver.blogspot.com, is interesting reading. He also has a website, terrymillerstudio.com. These sites have links to other nature artists. I really like Terry's bridge drawings, some of which can be found under "landscapes"on his website.
I've just begun a new pastel in the farm series. It's a scene from a country fair. The piece has several large draft horses which I've not drawn before.
