I really like the capture of the pine cone and the grass - excellent clarity and colour. But I agree with the earlier comments about the cone and the tree being too similar in colour. IMO, the cone is the star of this shot and the tree needs to fade away into the background more so it doesn't compete for attention. Either using a lens and aperture that will give you a much more blurred background or reshooting in front of a darker background would do the trick.
Oh yes, and do straighten the horizon.
