Framing a shot

For me I like to capture wildlife , this will mean following certain rules in photography to get the result I want. Framing a picture is simply using the surrounding fence, tree, window frame ,door frame . Making sure it is straight can make or break a picture . The Rule of Thirds is commonly used , this helps you position the subject to where you feel is most pleasing . https://en.wikipedia.org/wiki/Rule_of_thirds
My picture of the Magpie walking from Right to Left leads the viewer's eye across the picture , it is not quite central which helps to make the picture , with the help of the fence to frame it . Settings were Nikon 7000 , Tamron 70-300 , F5.6 , Shutter 1/320 , ISO 100 , 300 mm .
