Hi - a great photograph! A suggestion perhaps. Once you place a person, i.e. a live subject, in your photograph, he, she, or it then becomes the centre of interest in your photograph - whether you intended it or not. Thus, in my view, the other elements should be complementary to that subject. Thus I agree that some of the bottom should be cropped but only about 10%. However, I find that the rock and the (beautiful) warm mountain on the right edge of the photograph pull one's eye out of the picture and away from the fisherman. Thus I would crop the right side of the photo just at the left edge of the rock in question. Part of the left side could also be effectively cropped right of the white building. Does this help?
