Never have the main subject of your picture look straight into the camera. Unless it's a "portrait."
Never cut off people's body parts in your pictures, and don't leave extra empty space on the other side of the picture.
Always make sure the color balance in all parts of the picture is perfectly reconciled.
Those are rules. A good picture is something else. I like this picture. I don't like it because it breaks those rules, and likely many more. I like it because it works, and I don't pay any attention to rules when I make pictures.
