Use architectural lines – walls, fences, roads, or any lines to lead the eye through the photograph and draw attention toward the main subject.
In this photo, attention is brought to the bird in the tree. The exposure here is low and there is detail in the slight amount of shadows and highlights. The subject, the bird, is in clear, sharp focus. The depth of field here is semi-shallow. The back is blurred but it might've helped the photo to make the area around the bird blurred as well. The lighting is soft. It enhances the photo because it allows the photo to have finer detail. There is lack of color in this photo, it doesn't really pop. The bird is in a rule of thirds and spacing composition. There is lots of empty space in the area the bird is facing. It brings a sense of movement to the bird, as if it's looking around.
