I have to say that your aspect of nature is completely different from mine or what I think of when I look at the Littlefield tree. You mentioned three categories of nature but only listed 2. Make sure you check for small grammar mistakes throughout your essay. Your last half of the paper did a magnificant job describing nature from a different perspective. Not many people look at the sky in the way you and I do. I think it's always important to view all aspects of nature far or near to us. Overall, I enjoyed your paper...great job!
