My dog Sammy sitting on the porch, staring down a bird that caught his attention

This is a photo of my dog Sammy sitting on my front porch. This photo utilizes the rule of thirds as Sammy is on the right third of the screen, looking inward towards the rest of the shot. This helps suggest the motion in his actions, as by leaving open space to his left, it gives the feel that he has movement in this direction. This shot also has movement through the way Sammy is looking, as if he has noticed something intriguing and he is ready to get up and check it out. Another composition aspect in this photo is the leading lines that focus on my dog. The railing, the wall, and the shadow both draw near direct lines that emphasis Sammy.
