One of the things that's going on here is the bizarre (to me) combination of idyllic green scenery, a picture postcard sort of landscapey feeling togther with an HCB style decisive moment. The two fishermen are intent, it looks like a more or less intense moment. I think the framing is sort of stuck in a no man's land between:
- not close enough in to the action to make it exciting
- not far enough out to make it scene idyllic
This isn't necessarily a bad thing, but it does put the viewer off kilter.
Like the previous commenter, I don't like the centering of everything (shoreline, dude in white). The background foliage does not feel particularly fortuitously placed, it seems just a random collection of green masses. There is the one mass leading from the upper right corner down to the boat which is good, but it's like it's trying to be compositionally strong, but not quite making it. Not your fault, of course, that's where they were at that moment.
