I clicked on this deviation from the big watch list I had to review, because I really liked the strict rule of thirds. This is a very traditional approach to art, but I like that you still managed to add some asymmetrical balance by framing the boat in the lower right corner. My eye went directly to the boat... it's a very small part of the overall piece, but the contrast is from the pure white is overpowering on top of the cyan blue ocean.
It's a good shot. It's not "amazing" but it is good. My only gripe is that it appears a little soft. It may have turned out sharper if you were shooting at f/11 or higher. I'd love to see more detail in the water and feel the depth.
I can see this being used commercially as a post card from a coastal resort.
