And, you're showing a really good eye! I like the monochromatic feel to this picture. The placement of both horizon and the moon is great (though it might have been a little better to bring the moon a little more into the frame -- easier said than done, I know).
About the only "complaint" I have on this one -- and it's a bit of a nit -- is that the horizon seems to be slanting down towards the right a bit. Not much of a slope but it makes me feel a bit off kilter.
