Derek, The tree out of the top of the image is very distracting, can you 'clone' it out?
I had a similar problem last weekend and short of cutting the tree down I couldn't remove it from the image - Mine was closer to the edge so I added some vignetting to hide it - but you should be able to edit it out.
You can see mine in the top left corner -
