I think you got great color with this shot. It may be a trick of the eye but I am seeing a slightly leftward leaning horizon here... When I scroll the horizon to the top of the browser window it proves to be true by less than a degree. I also think this isn't quite sharp enough due to either camera shake or focus slightly off.
I like it, and it is very similar to another winner 9 year ago :) but you missed the sharpness on the yacht. I'd prefer it there rather than where it appears to be; on the sun's reflection in water bottom foreground?
