Great assignment. You’ve highlighted some of the most important compositional elements that should be considered for each of your photographs.
Your example is interesting because both images are simplified. What most students do for this assignment is take a chaotic, unorganized scene and organize it by moving in closer. This gets rid of distracting background elements, narrows the color palette and simplifies the edges of the photograph.
However, both of your photographs are simplified from the beginning so you’ve had to use other ideas to make your “beauty” stand out from your “beast”. You’ve done something incredibly important; you’ve prioritized color as your main compositional element.
Too often photographers forget about the importance of working with a color palette and understanding color theory.
Look at the following National Geographic photographs and try to identify their color pallets. You’ll notice most of the photographs work with about 4 colors (with varying shades and gradients).
