Autumn Ploughing

This week's AYMC homework is all about using composition techniques.
In our compositions we have to look at using 3s & 5s; filling the frame; symmetry and diagonals.
I'm not sure if this blip of the tractor ploughing in the field behind the church fits the final one. It suggests that diagonals create tension as opposed to straight lines being static. The lines are going at an angle but they are also reasonably straight. I don't think it's a particularly static photo but would be interested to hear what others think.
