Nice composition. Had you done some selecting of the trees along the left of the image to adjust curves or levels around them? There seems to be a light halo around the branches, which I've noticed in my attempts at selective adjustment.
The horizon needs to be straightened or all the water of the ocean will soon be on my desk, running out of the left side of my screen :shock: !
And I feel this photo is over-sharpened, hence the oversharpening halos around the trees on the left.
