This picture is Rule of Thirds because if you can see that the leaves from the tree are hanging down much like when you have long hair and it gets in your eye. Anyway the point is this picture isn't centered therefore it is not Rule of Thirds.
This picture is rule of thirds because the main focus is on the butterfly ,and if we were going to draw three by three lines in the picture then the butterfly would be on one of the corners in the middle lines.
