I love how the composition draws your eye to the background and the different blues of the sky and sea are lovely. It's kind of a shame the eye kind of skips over the island/hills to the left though, as its very pretty! Great job
Nice angle and perspective, but maybe less fisheye filter?
also, you might want to resize the image or only display a smaller resolution, because at the full resolution it is very blurry, and also, someone might try and steal it, and in which case you'd want to have the full resolution to prove it's yours.
