Rajan,
It must have taken a lot of discipline to not show a huge expanse of sky. You did the right thing and that harsh but correct decision cut off a lot of sentimentality and now makes this picture very precise in the motif of the descending sun. Given that I'd ponder on the lower 2/3 of the clouds that are present and I wonder whether they might have some reflection back from the water?
Good job!
Asher
