Here's my take on your picture's composition... hope you don't mind my tampering with it. This is a 2 minute photoshop effort so apologies to the PS experts out here.
I agree with the above comments... I would have zoomed out to include more of the sky... used the tree on the right to frame.. alongwith the fence below as my lower frame.
Finally, did you use a Circ Polariser for this shot? I have a feeling that the use of one would have made the colors (esp. of the sky and field) pop out more. Just a thought.
