Cropping

I'm a little torn about this picture. I thought the subject itself was intriguing, and that I got good exposure and light balance. I've done no post work on this shot. The question however is composition.

It's hard to spot your own best photos. What I like sometimes turns out to be very unpopular, whereas the shot that I whimsically posted turns out to be a critical success.

My brother suggested a tighter crop; remove the background characters of the 'lighthouse' and people, but I thought that gave the photo dimension and scale.

In thinking about it some more, I think I really would've liked to have shot from a lower angle and pushed the horizon to near the top of the frame. Of course, you can't do that in post work.
