Here are some great moments (statements) in photography. I hope you enjoy them and can learn from them.
I'm not really a wildlife photographer but I do think that Nick Brandt's images are some of the most beautiful photography in the world today. You should check them out at his website: http://www.nickbrandt.com/.
Gloria Hopkins' book "Natural Design" is one of the better books on composition for nature photographers. Here is the link: http://www.gloriahopkins.com/photographic_composition.html
