I think that this crop is better than the square one because it contains more imperfections. The square crop is kind of like “Hey, look at these big strong roots”, whereas this creates an entire scene. You see more struggle in this, the tree or trees fighting to keep hold in a steep, rocky place. I like the way the moss, in turn, is using the roots as its only way to avoid being washed away in the next rain. The roots off to the left, which are excluded from the square crop, are a little less impressive, yet; they are a little more gnarled, twisted, and not quite as big. Yet they are an essential part of the precarious web of life that you’ve captured. I also like the wrinkled bark of the tree that takes up the top left corner; it reminds me almost of an elephant’s skin.
The lighting in this shot has a nice glow to it; it is not bright, but is warm and very alive. Overall, it is a well-composed photo and demonstrates a good eye for the true beauty of nature; not the flowers and sunsets that anyone can see, but the basic fundamental qualities that make life so amazing.
