It's a beauty for sure. Since I am guessing you are on the beach or looking off the side of a boat, I must restrain my envy of not being where you were.
I love the buttery yellow of this sunset, with that wisp of cloud drifting past the sun. There is something soft and tranquil about it. But I wonder how it would look with the sea reflection taking up the lower two thirds of the composition, possibly in portrait format? Just a thought -- it's a peaceful scene as it is.
