This is an awesome shot - I think however, if you crop out the fishing boat it would be a perfect shot - just my opinion - very high score - good luck in the challenge!
maybe a little more sky to emphasize the challenge them, but a very nice shot in any event. I like the tininess of the fishers, it adds a lot of character.
Good idea, looks like good fishing weather. I would have placed the boat up a lot further following the rlule of thirds. I know it would have cut out the sky but maybe a lower shooting position would have taken care of it.
