If one has had intention of showing a scene similar to what could be observed visually, the edit is taken too far. On the other hand, if you wish to make a more distilled conceptual rendition of 'sunset', the colour scheme is acceptable. Only you can decide.
Either way, the silhouette of the fisher blends into the background in a less ideal manner. It ought to be captured 'free' against a water surface for a stronger impact.
