But the larger issue, in my opinion, is that the entire photo, except for the mountain ridge and sky in the background, is in the shade.
I think the main problem is not that most of the photo is in the shade, but that the logical centre of attention, the town and the fisherman, are in the shade, between two bright areas. I think it is am important distinction, because I don't care if 90% is in the shade if the right part is in the light. Problem here is that the wrong parts are in the light, jumping the eye right over the town.
The first point is dead on.
