I love the cloud/blue sky thing happening here. You could try cropping at the V of the second tree to see what you get. It would be a bit crowded on the right but the open space on the left would balance it out well.
I see that the pasture is greener now that it has rained a bit. I feel you are right about not putting this one in the challenge, as it would likely get a lot of "where's the rest of the tree?" comments.
