I think this would be much better if you had taken a step to your left when you took this shot. This would have kept the branches on the right from going so far into the frame and made a better border to the shot.
A sunset is like a joke - sometimes you just had to be there. They don't translate well into photos. An interesting foreground helps. This is a lovely sunset and it must have been specatular in real life. I like how the colors are richer in the water than the sky. I like the perfect mirror image. The branches on the right, do the add? detract? I think the image is better with the branches but would have been even better if there was, say, an interesting silouette of a tree. I know, as photographers we take what we get.
